The Sub-Mariner Stamp by John Buscema

 Sixteen years ago, this stamp came on a letter from a buddy who was miles away at the time (member letters?  you member!).  Second image is the water-logged copy of Sub-Mariner #1 that I got for a song, and the last image is my favorite Kirby subby, that I've only seen as a similarly tiny image on the back of the Marvelmania Catalog
