ULTRA-RARE ERROR Black Card With Vintage 1994 Duncan Midnight Special Yo-Yo

Search high and low through google and you won´t find this Duncan Midnight Special Yo Yo on this black Error card. I found a few of these at an estate sale. It appears that the Midnight Special Yo Yo´s that were intended for the Japan market were mounted on this black US Midnight Special package/card. I´m not sure if the were ever sold in the US this way, I was told they were not but instead returned. If anyone knows the full story, feel free to message me. The yo yo is brand new, never opened, one of a kind. A great addition that almost no one has in the yo yo collections.
