This reminds me of an estate sale I went to. There were a couple of records…signed by bands. One was a signed copy of Appetite for Destruction with all band members. Kiss Dressed to Kill and I think a Poison record. There were COA’s for all of them. I googled the company on the certs and it had a bad reputation for fakes so I passed. Could have had them all for under a grand but I am not spending money on fake signatures which these most likely were.

I would say the CE owners are good to “claim” the signatures are legit as it was how the game was sold and documented. Now if it were ever proven or disclosed by the band they never signed them or someone signed on their behalf well that is a different issue. Doubt the band would ever disclose that.
