Once upon a squiggle... you couldn’t get a lazier collection of signatures!
I can’t say much about most of them but I don’t see a brad Pitt signature that I recognise- at least not the way I’m familiar with and I’ve found him to be pretty consistent.
i have no idea about the others though
I see similarities in strokes with Leo, Mike and Zoe here. If this was offered to me, I would pass. PSA or not.
