Oh SDR..I see what you mean.
And I would never blame the dark staining on you jdip (or dsil?). Everyone from my era all knew that Betty Page was commonly known as "The Wicked Witch of the Yeast"....The spotting is probably vintage. Just looking at her leg positioning makes me suspicious.

I had that sofa! Only mine was white, but it did have a giant stain on the seat. Now I have another idea as to what it was. Thank you so much.
