I haven't been able to find another of these out there anywhere so am not sure its maker, but I think it's a great one, definitely with some good years on it. I'm a big fan of stacking toys, and all the better that it should have handles to roll it with, too! (Maybe perfect for flattening out Play-Doh!)
11 3/4" l x 1 3/4" d and great vintage condition.
