I recently had this Scarface 40x60 restored by
Lumiere Poster Restoration. They did a great job and they're nice people to deal with. It took a little longer than I had hoped, and a few things on it aren't perfect, but overall it's a huge improvement from when I sent it to them.
Before. It's difficult to see a lot of the damage - numerous creases, tears, damaged edges, pinholes, yellowing, stains (a few that ran almost the entire vertical height), etc.
After. It looks almost like new. Upon very close inspection, a few things are not perfect, but overall it's great work. It's really amazing how it was restored without backing, now it is a lot more stable long-term, as it was cleaned and de-acidified and with gel impregnated into it, and it still has the vintage aroma. A brilliant method for restoration.
