A spin top on a top quality pencil. The yo-yo retainer at the top of the pencil is rather unusual: marbled plastic.
Manufactured by Hassenfeld Bros. (better known as Hasbro) of Pawtucket, R.I. This version of the pencil with a yo-yo on top, mounted on a full length mint card, is hard to find.
See the other exhibit examples for alternate versions.
