X-Men #34 and Dan Adkins

1967's X-Men #34 was an early Marvel penciling assignment for Dan Adkins, and back then the fanzines quickly pointed out just how heavily he'd relied on reference--check out just a few examples below (there are many more in the issue; take a look through it). Naturally Adkins looked to the Kirby X-Men issues for guidance--but guess what comic the second panel (Angel flying) is based on.

Yes, the pose is a standard one. Adkins repositions Angel a bit.

Popular Panel Composition by Kirby, Tuska, Kane and Adkins

I know Kirby wasn't the first to use this rather standard composition, but I'm still betting Tuska, Adkins and Kane each had a copy of Tales of Suspense #60 nearby ;) 

1964: Tales of Suspense #60 Jack Kirby

1966: THUNDER Agents #8 George Tuska 

1967: Tales of Suspense 91 Gil Kane. 

1967: X-Men 34 Dan Adkins

• Fun fact: Both Tales of Suspense #91 and X-Men #34 were on sale in July 1967 (so, in preproduction around the same time). 
• I posted the Tuska version previously, but I'm including it here so you can compare it with these other Silver Age panels.
