fkwIve owned about 4-5 of the W572 Neilsons over the years, all were (mis)graded by PSA and 1st showed up around 2000, at least thats when I first heard about them. They have been listed (w/story, no values) in the SCD Guide for many years now. Im not sure exactly how they figured out the print on back is not vintage, but its been known for some time now.
For what its worth, they are rare
