This is the original logo die stamp used to make the Smithsonian Institution yo-yos from Hummingbird. The Smithsonian custom was a larger order for Hummingbird, and one of the more popular advertising yo-yos. The logo was hot stamped metallic, as the shallow logo and machining suggest.
The logo is etched in reverse on the plate, and the plate was pressed hard against the wood to impress the logo. A one-of-a-kind Hummingbird collectible.
