The high acidic content in most poster paper can cause brown
spotting (foxing) or “Burn” marks along folds and creases.
Frequently, posters are just plain dirty with sometimes decades
of built up grime accumulated. With care, we can delicately
wash paper before mounting or soak the piece in a mild stain
reducing solution that can safely enhance the poster without
compromising its original condition.
These two 1950's luxury railcar flyers were both similarly
discolored when we received them. On the left, the paper is
shown before treatment. The one on the right has been carefully
cleaned before further restoration commences.
