Hello, I received this signed Mantle postcard 20+ years ago and I’ve suspected it was a forgery this entire time since it most likely came from eBay. It’s on a 1989 Perez Steele postcard numbered out of 10k which I’m certain is real. Unfortunately, it looks like it was signed with a thick marker or pen and there was likely some ink bleeding due to the type of paper the postcard was made of. I thought I would get some opinions before tossing it. Any help would be greatly appreciated.
