I bought this from a reliable seller a while back. I have no doubts about the signature, but I just hope it's real ink. I'm not very familiar with fountain pink of this color (which I'm assuming it is). It's a cut from fairly thick page - smallish about 1 inch by 2 inches, cut by the seller to sell the signature on the reverse as well. The top edge of the page is gilded.
Does this ink look like what a vintage ink fountain pen signature should look like, or could it by any way be something printed?
