Dear,
often occurs on a solid auction, offers graphic mid /late 19 th century in almost perfect condition.
The question is: is there a restoration technique, which allows to restore the yellowed, stained, rust, paper 19-th century to the white "as new"?
Expect that the yellow tint around the picture can be removed. But is it possible to remove the yellowing under the picture?

Almost perfect condition - the result of proper hraneniya.Vlaga, temperature and sunlight - adversely affect the safety of bumagi.Krome addition, when dealing with rarities on paper needs to wear thin cloth gloves t.k.ostayutsya fingerprints manifested over time spots.
Do not see the point in "clean" yellowness and "fox spot" because it is one of the signs that the paper is not today.
Here's how to remove zateki, when the old paper or cardboard gets wet and formed "halo" I do not know. 'll Show if anyone knows.
