Fantastic Four #168 (Pt 4) Ben and Johnny Storm Out--Plus Profiles

More Fantastic Four #44 and #168

1965: Fantastic Four #44 - Jack Kirby                              1976: Fantastic Four #168 - Rich Buckler     

Let's face it--it's pretty clear that Buckler had #44 nearby. Here's an example of how #44 helped suggest character position/placement within a panel, with Johnny and Ben:

Top: 1965: Fantastic Four #44       
Bottom: 1976: Fantastic Four #168 

                                       

Fantastic Four #168 (Pt 3) Johnny On the Spot

Top: Fantastic Four #44 (1965)  Jack Kirby

Fantastic Four #151 (Pt 14) Mahkizmo and Gorgon

1974: Fantastic Four #151 Buckler

1965: Fantastic Four #44 Kirby

Fantastic Four #150 (Pt 24) Reed, Johnny and Ben--More Profiles

Reed    1974: Fantastic Four #150 Buckler

Johnny   1965: Fantastic Four #44 Kirby

And that corner shot of #150 Ben might be based on a different panel from FF #44:

1965: Fantastic Four #44 Kirby

Fantastic Four #150 (Pt 20) Put Your Hand On My Shoulder: Ben, Reed, Triton and Gorgon

1974: Fantastic Four 150 Buckler

Fantastic Four #151 (Pt 8) Mysterious Medusa

Fantastic Four #151 (Pt 7) Medusa on the Move

Fantastic Four #151 (1974) Rich Buckler

Fantastic Four #44 (1965) Jack Kirby

Fantastic Four #151 (Pt 3) Ben and Johnny, Two For the Road

This one's a combo. The trench-coated Ben seems to be adapted from FF #68, while Johnny is from #44.

Plus, because FF #68 is used above, I feel it's the inspiration for this panel too.

Fantastic Four #150 (Pt 4) Ultron and Ben Grimm

Fantastic Four #150 (1974) Rich Buckler

I'm sure there must be plenty of prototypes for the Ultron pose (such as in Avengers #57) as it's a fairly standard "attacking antagonist" pose, but here's the image that immediately came to mind:

Fantastic Four #71 (1968) Jack Kirby

Also, here's the Ben figure:

Also, Medusa in the #150 panel is reminiscent of Medusa in this panel from 1969's FF #82. We'll see this Medusa image used again in another issue.
