Just terrific color and excellent optical effects when one sets these old tops spinning. I have had one of the larger ones before, which features four tri-color tin litho disks with serrated edges on the face of it, each overlapping the next (looking as if they might themselves turn like wheels but they don't), but this is a rare one for having its original layer of protective celluloid film over top of the disks. The smaller has a bell inside, which rings when spun.  

Larger: 6" d x 3" t. Yellow/red: 3 3/4" d x 3 3/16" - with a bell in that one that sounds when spun. The larger is spun by holding the sides rather than the handle. The smaller is spun by the handle and doesn't spin for too long, but is mesmerizing while it does!
