>Earlier in March, a brick and mortar store in Ohio called Table Top Gaming received a few hundred boxes of Yu-Gi-Oh cards from a distributor and found something strange inside. “The printing company packed the pallets with the test print sheets by mistake thinking they were just blank sheets. Pallets went to distro then me. I didn’t acquire them in any malicious way so I thought they were safe to sell, considered abandoned property because they were intended to be trashed,” Table Top Gaming owner Tyler Jedlicka told 404 Media.

>Jedlicka says he posted the test print sheets online and Konami contacted him. The company wanted the sheets back. Konami runs the official Yu-Gi-Oh tournaments and angering them could mean hurting a brick and mortar business, no matter how rare and expensive a test print might be. “Once we confirmed in writing with [Konami] the blame isn’t put on us and that our status as an official tournament store won’t be affected we agreed to return them all,” Jedlicka said, adding that the whole thing was resolved without a major issue.

Sounds like the mistake happened more than once but not everyone was dumb enough to sell them under their own name.

It doesn't just sound real. Blank sheets are vastly different size from shipping boxes for packed product... And printing company would not ship blank sheets. And distribution company would not forward something that clearly looks wrong...
