Let another speak to authenticity. Each looks a little odd to me. alone. I - this is just not my strong suit or anything like it. I note a few things - Jagger baseline. Oddness in Brian Jones. I'm out on a limb here. But I say. Do thses not appear the same hand - spatially - style? Stroke?
Fake. Buy from Tracks if you want a RollingStones nice and 100% authentic. In the "poor auctions" there are many fakes... RR and Iconic auctions are good.
