Yes, Dan, certainly I have to check the seller. He has lots of good ones, but also some well known secretarials. So obviously he is no expert and therefore cannot be trusted blindly. That's why I'm asking the community.
Once upon a time in this forum there was a discussion about Knightley. Some smart words had been written about recognizing an authentic sig by the bottom line, but I don't really remember. Would anyone mind to repeat it?
