Flea Market Find

So I found this odd little shelf/compartment "thingy" at a flea market for $5 and had no idea what it was...It was originally an ugly grey color and the cashier and several other workers also couldn't tell me what it was used for. I slapped a coat of this green paint on it (mixed with Webster's Chalk Powder) and sold her for $25. Having paid only $5 I wasn't scared of "ruining" it with the green paint but people really responded to it.
