This is the second version with one rhinestone on the center of the face. For the riveted version, see Goody Master (Riveted).
The Master is a yo-yo produced by Goody in the late 1940s to 1950s. It came in two versions; this is the latter version.
It came in various colors, sometimes with a gold stripe on both sides of the yo-yo. On the face side of the yo-yo, there is one white rhinestone on the center of the face.
Unlike other manufacturers at the time, Goody drilled the jewel holes after the yo-yo was painted, so the user can see bare wood around the edges of the jewels.
This yo-yo is listed as #628 in Lucky's Collectors Guide to 20th Century Yo-Yos.
