Here is a yo-yo collection unto itself! All in good used condition. Thirty-one (31) model 33 Duncan yo-yo’s turned at the Luck Wisconsin plant. None bear the name Duncan on the reverse side! All are advertising yo-yo’s including Burgerville USA, Dodge Trucks, So Good Potato Chip Company and Tape City Car Stereo Center to mention a few. Nothing later than 1992. Over 50 years old impossible to collect today at twice the price, particularly with shipping costs. Lucky winner will get the history of these gems. What you see is what you get.
