Ha! This is fabulous. :)
This is really interesting! Although I must say, after seeing the stool in the photo I can't stop imagining a little invisible tuffet hovering under her train in the painting. It's also interesting to see the brace holding the man's hand up in the photo, and the reduction of the woman's waist size between photo and painting.Have you seen the similar comparisons people have done for Norman Rockwell's paintings? It can be fun to see the small changes he made and guess why he made them.
