Dear All
Hope all is well and safe. I joined few weeks back. You can read a little about me in Introduce Yourself section.
I would like your thoughts and opinions on a linen backing and "restoration" job I had done at The Movie Poster Art Gallery Colville Place London. It is somewhat long winded description so please bear with me.
I wanted to have their response before I post my experience with them.
After finding a decent enough copy at eMovieposter, I took it to be linen backed. See Original

I met Martyn who was pleasant enough at the time and assured me the folds will come out ok, with an estimate of 6 weeks or so. He charged me £200 for the backing and £40 for light restoration.
After missed deadlines, poster was linen backed and I went to inspect it at the gallery. At the time it looked ok to me and I took pictures.

After it was delivered to me in late Aug I had the poster still wrapped in my living room while procrastinating/ discussing with the family as where to hang it, etc and this was finally done around Xmas 2022. Room was normal living conditions and I have had US 3 sheet of Live and Let Die on a similar wall without any issues for a few years.
The closer I looked at the poster I noticed more and more "rippling" , some air bubbles and some tears.

Air bubble?

What really broke my heart was the two tears that noticed.

I contacted MPAG in early Feb and they told me poster was a perfect example of restoration and asked me send photos. Told them that I had US 3 sheet on similar wall with no problems.
Here is what they told me after being prompted for a response repeatedly.

Yes I see what you mean .
Certainly the paper has been shocked and this ripple is 100% consistent with humidity changes. It was 40 degrees for a while in summer and dropped minus 8 in London in December As you know the separation certainly was not in it when it left here. It left here in fine condition. But expansion and contraction has obviously found a week spot in the papers weave as it is 50 years old. The only thing that makes paper move like that are humidity changes. This can be caused by temperature changes /air conditioning /sunlight Your poster was backed with all reversible conservation materials and has been with you 8 months. Overall its protected and the movement is cosmetic, the separation is fixable . Your other three sheet poster may have been mounted in a permanent non conservation way and fixed in place .
Have a quick check to see if the back of the frame is free from mould . If we can help in some way this is an unusual and rare occurrence i'm sorry your enjoyment has been curtailed .

Told them poster had only been with me for under 6 months ( I called them in early Feb) so missed the Aug heatwave, there was no mould and separation was there before the poster was shipped, per photo I took in gallery in August, which I sent them.
Again after a lot of prompting I got below.

We have reviewed your photos and comments and feedback is below based on our extensive expertise with decades of experience in conservation and framing of literally thousands of original vintage posters
The image you sent is not evidence of a tear but is part of the fold line.
Your poster was folded as you know. This is a sign of originality for the GB Godfather 3 sheet as they were folded for distribution to the cinema. From our photo you can clearly see this intersecting machine fold. You can see it runs horizontally and crosses the vertical fold also running very close to the black border of the artwork. This is difficult to see in direct light or in low light and also low quality photos from a phone.
On your photo that you took pre linen backing we increased the contrast and you can clearly see the areas of crinkled paper adjacent to the fold . The paper fibres are stretched and warn along all these points. Although your photo doesnt show enough detail its clearly there.
The top left section of this poster was the final machine fold. This fold had to stretch over the entire thickness of the rest of thefolded poster hence the crinkled look in our photo. Every single folded example of this poster reveal this to be the area where the paper fibres are stretched and worn All the posters are machine folded in the same way with a top left fold intersecting with a vertical fold running parallel with theartwork black border. This fold takes the most stress when stored or posted out or distributed to the cinemas at the time and with each opening and closing of the poster. All of the GB Godfather 3 sheets are heavily folded onthicker paper than a standard quad poster. So the folds are deeper and become more creased. Remember you poster has been stressed along these points when opened and folded and stored for up to 50 years.
Linen backing stabilises and minimises this but does not in itself make fold lines invisible. The only way to make these warn areas ‘invisible' is to do a practice known as airbrushing which covers it with a fine layer of paint. Airbrushing is practised widely in the U.S. for clients who want their posters to look perfect but also can disguise damage in a poster. However paint ages differently to paper and given time the airbrushing can be revealed making the poster look worse. This is not a conservation method.

And they sent me photos below.




I told them only one of the tears is along the fold line and the other is not on the fold line. And they can check this against my super res original photo from eMovie.
And I got this

Mani your now saying that there is further damage done by us. The auction photos are only proof of the poster when it was photographed not when it was posted out and handled before it reached us . sometimes auction houses can pack and handle badly or even the postage damage items post sale , also you yourself have handled it. I have told you Mani If we ever have an issue with a poster we would have told you. You seem to think that we are hiding something from you which we would never do.
On a different tack , the poster doesn’t actually need re-backing. just pressing. This can be done using 10 mm acid free foam core to restore its flatness. Your local framer could do this

So Dear All, sorry for the long story. Their story does not make sense to me and it certainly seems to be changing with every email. And I cant see any fold lines along the second tear even in the B/W photos they sent me themselves or perhaps I am missing something. Would appreciate any thoughts or opinions on this job.
As for moving on if I want to have the poster flattened as far as I can see, now I have two options:
Taking the poster out of frame, sending it to US via Antikbar to remove and reback at cost of £500 ( and then a new frame if poster too big?).
Or have the foam core solution that he suggests?
Would be grateful for any thoughts and suggestions.
Mani
