Duncan Butterfly model with the World Yo-Yo Contest imprint on one side cap only. From 2000.
The World Yo-Yo Contest of 2000 (aka the 2000 Worlds) was held July 8 and 9 at Nickelodeon Studios at Universal Studios of Orlando, Florida. You can still visit the official 2000 Worlds website here -- at least what's left of it. (Retrieved 19 September 2020)
This model of Duncan Butterfly is hard-to-find. At the time, Duncan was not known for making custom imprints for events or yo-yo players. That all changed when the Duncan Freehand was introduced in late 2000.
Original retail price: $4 US.
