This is the die stamp used to produce the Yo-Yo Man logo side of the Second release of the Hummingbird Smother's Brothers Yo-Yo Man Yo-Yo. The second release logo did not have a ring around the logo, and "Hummingbird" was added to the logo. The logo is etched on the plate in reverse. In this case gold foil was impressed onto the yo-yo half with the plate. A "one-of-a-kind" Hummingbird Collectible.
