Without divulging anything you don't want to, how were they discovered? I love a good wacky pack story.
Sorry no exciting story here, no misleading information about a vending machine that never existed....just boring me buying sheets from a dealer who had gotten these from a friend who he believes worked for Topps many years ago. Unfortunately it is difficult for me to get more than a sentence response from the guy I got the sheets and he says he and his friend don't have any more Wacky package stuff. I tend to believe him since he had dug out the 2nd and 3rd sheets after I asked if he had any more wackys. Nothing else has surfaced.
I wonder if Topps had toyed with the idea of changing the sticker stock and these are not proof sheets at all. They are coded exactly the same as the regular series 13 sheets, have no odd proof or color spectrum colors along the edge like many other proof sheets. I wonder if this transparency sticker sheet didn't cut as well, maybe it was a cheaper option that didn't work out so they scratched it.
