Museum of Yo-Yo History
This museum of vintage Yo-Yos, originally based on David Hall’s collection, offers dozens of pages of vintage Yo-Yos, with high res photos (often multiple views), text descriptions and specs. The site also offers a Yo-Yo memorabilia section with patches, photographs, some very cool pins, and more. Note that to see all the items in a given category (including the Yo-Yos themselves) you must use the pulldown menus and click browse, after you’ve entered the exhibits area.
