The Aero lp looks like a fake to me for sure.
The Bryan Adams has no similarities to a couple of lps he signed for me,I think its a fake as well.
I don't think any of these look remotely authentic.
I've only got a Police, U2, and Aerosmith of the bunch. Oh, and a Bryan Adams. But I've seen lots of examples of the other bands, and these look absolutely horrible.
I'd like to make a suggestion.
On threads like these -- you have experts (Roger) and people like me (that have seen hundreds of these bands signatures), giving our opinions.
It seems after we've given the opinions, the person that made the purchase -- or you Steve -- should tell us WHERE they bought them. Even if that means "at an estate sale" or "saw them at a record store," or whatever. Sometimes it helps, when we can all say "Oh...Autograph Central. That explains it." It helps get the word out for the bogus places selling these items.
