Leather

One our special collections staff asked about yellow stains on
contemporary white leather furniture.

The furniture (which is functional, not an exhibit piece), is
exposed to light, but not direct sunlight. But yellowing occurs in
spots, rather than all over.  To the best of our knowledge, the
stains aren't the result of spills.

Any thoughts about what might be the causing the localized stains,
how the damage might be treated, or what could be done to prevent
further damage?
