Is this water damage?

[pratschm]

Not sure if this is the correct sub-forum, so apologies if it's not. Guess we could always talk about how to fix it and then it'd be ok. Anyways...
Came across a 1-sheet that had the accompanying image. Asked the seller if it was water damage, but they said they wouldn't know.
It looks like it to me, but I don't have that much experience with that type of damage. Could possibly be just wrinkling due to <insert reason here>.
It only appears at that location. I don't see anything similar in the top border (eg, water damage while rolled). Perhaps crimping due to a frame?
Your input would be appreciated. Thanks.

They look like "compression waves" to me.  I see them all the time on posters that have been in frames that are too small OR sometimes in flip frames.

The damage is always permanent - you can't press them out just with heavy weights - but definitely could be fixed with linen-backing or maybe heat press.

If it's not worth sending to a restorer, you'll just have to live with 'em.

Thanks, Mel. I was hoping you'd respond. I think you mentioned in another thread that you'd seen crimping with some of your posters and frames. Thought you'd have a keen eye for it.
What is this heat press you speak of?

There are alot of pinholes too.

what about trying to iron the paper to see if you can get rid of those marks? Id thought one could do that....

I wouldn't try an iron on a valuable poster.

I wouldn't even deal with this copy or those rippling issues. Just wait and look for another that is in better condition.

This poster is fairly common.

Nice read, Mel. Thanks! Little more than the 2 towels and an iron I was hoping I could do. Oh well.

Looks like moisture damage to me.
And those pinholes look like staples.  How bad are the other corners?

I've been thinking about this one quite a bit...  I have a theory that I need to test out for spot water damage or just spot removal.  I know you can starch back and then peel it off the holytex...  I think I can get it done with some MethylCell a piece of Holytex and a hobby iron...  Anyone have a candidate?  I can look through my spares first I guess or intentionally get one wet...

Was thinking that, too, Ted.. they almost appear to be humidity-induced ripples or waves. 

I remember years ago, as a kid, when living back east, having a smaller concert poster in a cheaper frame. The poster was not snugly set into the frame. I grew up in a hot, humid summer climate. The poster developed very similar looking wave patterns, too.

Sorry, I don't have any more information. I passed on that particular piece. Just recently acquired another one in pristine condition and for a lot less.

Hey Charlie.
I don't have a water damaged one, but I do have that one with the foxing. Would that qualify for spot removal? Or do you mean water/oil/gunk spot removal?

Right on, Mike.

Congrats.

Thanks, Jeff.
I took your advice.
