"I've had good success with floating seriously fauxed prints in 25% hydrogen peroxide solution, though I've had a couple of dramatic failures as well."
About the fauxed / foxed prints -
Is the "25 percent hydrogen peroxide" a typo as well (over-the-counter H202 is about 2.5%)
25 percent would destroy many of the colors of this print immediately. In the early 1800's they were all-natural plant-derived colors, some of which are sensitive. Anyway, this particular print should not be immersed in any kind of solution, because some of the colors are water-soluble, also the mica might float off the surface of the paper. Don't do it...
There might be a way to locally reduce the spots in the background in the left. It would be interesting to hear the verdict of a professional conservator.
