Audubon colored print. Notice the severe light damage before treatment.
Picasso print. Tape on top edges, and mat burn on margins. The image is on a tinted background, which is not to be mistaken for light damage. Notice the orange ink signature. Protecting the signature was vital.
This is a Gould hand colored print. The yellowing and mat burn really detracted from its beauty.
Another lovely Hans Kleiber watercolor. Before treatment, tape was surrounding it.
This little O. None watercolor had severe light damage. It is now much improved.
Notice the ugly rubber cement surrounding this Japanese colored wood block print.
