Giant-Size Avengers #1 (Pt 1) Opening Splash

Sure, on the face of it this is a fairly standard superteam group shot. But there was something awfully familiar about the characters' positions, especially Cap's dramatic pointing finger and Iron Man's very awkward crouch.  And then--it hit me!

Giant-Size Avengers #1 (1974) Rich Buckler

Fantastic Four #82 (1969) Jack Kirby

                                             

Panelocity Plus! GSA #1's Cap figure also seems based in part on Sal Buscema's dynamic, Kirbyesque Cap on the cover of Avengers #71 (1969). 

Roy Thomas wrote GSAvengers1 and Avengers 71--as if you didn't know already know that, since both issues spotlight some legendary Timely Golden Age characters...you know 'em as the All-Winners Squad/Invaders.  ;)  

And I'm sure all you True Believers noticed and appreciated Buckler's fine recreation of the very famous All Winners Comics #19 cover (as the Whizzer relates his days with that fabled team).
