Courting Couple Tapestry

I found this in a box of fabrics I purchased at a yard sale a few years back. I'm not sure how old it is or what it was even intended for but I plan to create something the piece. I'd like to know a little bit more about it before I cut into it and create an altered tapestry/embroidery with the piece.

I have some beautiful quebracho dyed silk dupioni that I plan to use for the borders, both in a steel gray and a lovely rose color ;-)
