Hi guys, looking for opinions on this signature, but it's not as much about authenticity (though opinions are welcome!), but about how to tell if this is a reprint or not. I have examined the ink with a 7-power loupe and remain undecided. Any ideas? Thanks a bunch.
Unless it is a photographic copy of a NASA issued lithograph, it's not a reprint. If it's the original NASA lithograph, it is NOT a reprint.
It's easy to determine a printed signature on a glossy photo. However, it can be more challenging with the lithographs because marker ink can sink into the porous surface. The ink doesn't appear to "sit on the surface" the same way it does for a glossy photo.
