DC Comics Presents #69 (1983) Superman & Blackhawk Cover by Irv Novick and Dick Giordano

Check out this awesome battle cover as Superman and all of the Blackhawks charge ahead to battle the Nazis! The big head in back ground is Professor Einstein on an acetate overlay with an extra inked drawing of the Einstein figure again on a large piece of vellum. So this entire cover is all drawn artwork with 2 Einstein heads. The cover was made in summer 1983, and published in May 1984. Personally I think Novick really nailed the look of Superman here, Superman looks exactly how I'd like to remember him. Even my mother-in-law (born in 1953) was impressed and said that this is an awesome drawing of Superman, and she cares very little about comic art :-)

Furthermore: "At the height of his popularity in the early-1940s, Blackhawk titles routinely outsold every other comic book but Superman. Blackhawk also shares the unique distinction of being just one of four comic book characters to be published continuously from the 1940s through the 1960s (the others being Superman, Batman, and Wonder Woman)" (Wikipedia).
Thus at least for historical reasons, having both Blackhawk and Superman on the same cover is very special (and as a scientist, seeing Einstein's face is always inspiring ;-)

Also, note the 3D-like "pop-out" effect on this cover by the thrown grenade and Superman's left fist - really making this cover come alive!
