Since I am unofficially the sig-stamp queen, how 'bout a tour? I don't know what I carve more of...sig-stamps or Star Wars stamps! There's some oldies-but-goodies in this stack, including my first (So. Hill WA).
Sorry I can't give you sizes on these - I guess the more pixelated the image, the smaller it is! (The smallest sig-stamp I have is 1/4"; it's the SHH in an oval.)
