A custom yo-yo made for Comet. An example of Hummingbird's advertising yo-yos, rescued from the liquidation of the Hummingbird factory.
While this ad yo-yo appeared in one of Hummingbird's catalogs, under custom yo-yos, we are still unsure what company made this, and what it promotes. If you know more about this one, please contact curator@yoyomuseum.com with details.
