I have a red, white and yellow Duncan Butterfly around somewhere, vintage 1970.
If anyone ever gets up to Chico, CA, there's a sporting goods store downtown with a very cool International Yo-yo Museum in the back corner. They've got 400 to 500 yo-yos from the 50s, 60s, 70s, and 80s. Very comprehensive collection, many still in their original wrappers.
