This is a rare and interesting golf ball yo-yo. From the Duncan portsline of the early 1960s. It is in good condition and all the red stamp is readable with no visible chips or scratches. Would probably clean up nice.
This was a released prior to Duncan going bankrupt because of the big lawsuit with Royal. They were actively promoting this yo-yo, but had to kill the campaign when they went broke.
The smaller stamp still shows the registration mark on "yo-yo" which is what the lawsuit was about. You don't see these very often.
