Mr. Infantino and Aquaman didn't cross paths very much; anytime that he got to draw the Sea King in a comic it was usually in the context of an appearance by the entire Justice League of America. So even though he wasn't all that familiar with the character when I met him (still doing conventions at age 83!), he generously agreed to do the sketch, and went above and beyond by doing this half-body shot (despite the protestations of his booth handler, who wanted Mr. Infantino to stick to headshots of two or three of the characters he was most associated with).
In addition to his staggeringly long career as a comics artist (where he was involved in the creation of characters like Batgirl, Black Canary, The Elongated Man, the original Phantom Stranger, Deadman, Animal Man, and a little speedster named The Flash), he was also DC Comics' Editorial Director, in charge of designing some of the company's most iconic covers, including this one:
