Jack Kirby Kung Fu Fighter Original Artwork! I believe it's from issue # 3 of the book, but if you look at the scan you can see it says 4, with a 3 above it. The page is signed by Jack Kirby in the 2nd panel, and there are productive glue stains on the edges of the page (see scan) outside the artwork, and a tape stain at the lower right of the page just into the artwork area.
There was probably a "continued after next page" type message there that left the tape stain. There is a blue pencil correction line in the 4th panel which is also visible in the scan. These are all relatively normal production markings, however, I like to mention them to be completely accurate. The page is inked by D. The item "Jack Kirby Kung Fu Fighter Original Artwork!
