Thanks for pointing this 'fake' board out, Steve. I never noticed it. Here's one I'd like to show. I think I may have posted it on SCF a few years ago, but never got an answer. The overprint and cancelation on this stamp make me suspicious. The overprint converts this Spanish stamp for use in Puerto Rico. But I find the cancel and the overprint to be made of identical deep black ink. Looking up close with a loupe, theres no differentiation between the two, which makes me think they were applied together.
