Jack Kirby had a few of these at a convention in the late 70's. The paper is thin and easily damaged, as soon as Jack signed it I took it to my car for safe keeping. Since then I have never seen this poster offered for sell.
It is reprinted in a book (early 80's). The item "Signed jack kirby Silver Surfer Poster! One of a kind" is in sale since Saturday, June 9, 2018. This item is in the category "Collectibles\Comics\Posters".
The seller is "sellurcomics" and is located in Youngstown, Ohio. This item can be shipped to United States.
