Miles, I cannot definitely say anything about the signature on this item (item=2256846255)
But I have purchased Titanic items from this seller. He was reputable in my dealings with him.
And very honest, did not try to charge too much for shipping. He , at one point was a big Titanic collector and had some very scarce, (and I mean very scarce) items, to go on Ebay.
Saying that, I again, reinterate, I cannot verify the signature as authentic...just telling of my
experience with the seller.
Sincerely, Patty
