Fantastic Four #117 (Pt 3) Sue and Reed--Plus Ben

Was Buscema inspired by Kirby here? Maybe, maybe not. But his positioning of Reed and Sue reminds me of the cover of FF #41.

And yeah, I know you're already familiar with this #41 Reed 'n' Sue image; after all not too long ago we saw Buckler use it as a basis for Captain America and Mantis in 1974's Giant-Size Avengers #1, remember? ;).

Plus! Now, take a look at the panel preceding the Reed 'n' Sue panel in #117: 

That's right, it's big, broad-backed Ben -- same camera angle/POV as Ben on the aforementioned FF #41 cover!  ;)
