A one-piece maple wood Royal yo-yo from the late 1940s or early 1950s. One of the few Royal yo-yos that did not use a royal crown in the stamp or, in this case, the decal. There are four "jewels" on each halve of this simple but beautiful yo-yo in a classic tournament shape.
When the yo-yo was manufactured, the holes for the jewels were drilled first. Then, the yo-yo halves were painted. And finally, the jewels were cemented into place.
