Hoping that others might have an idea. I think this Brando signature is good (although feedback pro or con would be welcome).
My question is more what kind of ink has been utilized. The seller states it is a fine felt tip but I think it looks to be more of a vintage biro ballpoint. I've included a highly contrasted image as well. I see scratchier aspects of it, skips, some slight bleed off of the letters and aging that looks more ballpoint.
