Maris, Mantle & Berra Auto - Any chance?
 

So, I don't really collect autographs but I know the majority of Mantle signatures are bogus. This photo belongs to a friend who recently acquired it when her brother-in-law passed away. I told her I would ask other collectors if the signatures are any good before attempting to sell it for her.

The photo is printed on HP photo paper which already makes me suspect but what do I know? :)

Thank you for adding the HP part, otherwise you would have had a lot of accidentally misinformed answers!

The original was authentic. As you have guessed, this is obviously just a copy, printed on a home printer.

But the pixelation is also a dead giveaway.

In person, it certainly looks like these are actual signatures (authentic or not I don't know) on the photo. Hmmm

Well, they're not.

That HP logo paper debuted in 1999. Roger died in 1985.

Thank you! I tried finding that info online but came up empty handed. I will let the owner know the bad news. Much appreciated.
