This is a total long shot, but my husband sold a small needle-point wall hanging in a frame with a train on it at a garage sale we had about 2 years ago.
His grandma made it for him, and he's having serious regrets over selling it. Our 1.5 year old is now obsessed with trains, and it would mean the world to him if he could get it back.
We'd buy it back obviously.
It was sold to a 35-50 year old Hispanic man at a garage sale on Williams Street in Downers Grove (by Dominicks and Trader Joes).
