This is a wonderful find, it is the 1960 Ford Starliner Convertible from Tootsietoy. Released over 50 years ago, it is one of only 4 cars taht Tootsietoy built in HO Scale. They are all nicely detailed for this scale, and this one is in nice condition with minimal edgewear, and the trailer hitch in tact. 

If you collect Ford, Starliners, Tootsietoy, or have an HO Scale train layout, this is a great find for your collection/layout (1:87 Scale)
