Wow! Thanks to the fine folks at GIL KANE UNCHAINED (seek them out on FaceBook), here is a fabulous and rare Gil Kane rough sketch design for the cover to AVENGERS # 138! All of Gil's famous mastery of anatomy, action, and direction are on dynamic display here, as the "assemblers" rush into battle against the savage Stranger in this 1975 cover scene! BONUS! Dig how the 7-11 folks re-figured the finished art for their sensational wrap-around Slurpee cup design, fresh from the sizzlin' summer of '77! How many characters can you name? Click to enlarge!
