Dog Lithogram: $5150

Maureen Flaherty went to the opening of a Goodwill store in Florida back in 2015. There she came across a lithograph print of a canine on the wall. She paid $44 for the painting and was told by an antique expert that, “you just walked out with the most valuable thing in there.” She went home to realize that it was the painting named “The Brook Hill Dog” by Alexander Pope. She sold it for $5,150 on eBay.
