When I was a kid, I spent a whole lot of time with friends performing improvisational dance routines in the living room or back yard, on which we would rate each other at the end. They were ridiculous (the Grease soundtrack, Cats, and Cyndi Lauper all featured,) but finding these numbers made me think of how much it would have added to the proceedings to be able to hold up these numbers to deliver those ratings in very official style! So perhaps the perfect gift for a 10 year old, but surely also useful in all sorts of other ways, and who doesn't like to judge? (Just be kind and err on the high side when the performer is young and awkward!)
8" x 4" each. Bound with metal rings, which unlatch, each double sided, with progressive numbers on each side (i.e. front is 0, back is 1). Good used vintage condition.
