The weirdest thing I saw at the antique mall in Springfield

I was looking for old picture frames last weekend and saw a glass case full of family heirlooms for sale. One item was a single, very worn leather glove with a tag that said 'Great-Grandpa's driving glove, 1928, $45.' It just sat there all by itself. Who sells just one glove from their family? I had to laugh. Has anyone else seen a lone item like that and wondered about its story?
