Fantastic Four #141 (Pt 3) Sue Reaches Out

1973: Fantastic Four #141 - John Buscema 

1965: Fantastic Four #39 - Jack Kirby

Psst--look at Franklin vis-à-vis Ben. ;)

Verdict: Eh, pretty standard. typical positions. 

Fantastic Four #138 (Pt 2) Johnny Storm, Sweet and Innocent

Okay, it's a stock facial expression, but in #138 Buscema's callow, slack-jawed Johnny (a flashback to FF #3) always strongly reminded me of...

1973: Fantastic Four 138 Buscema-Sinnott

...Johnny from Fantastic Four #39. 

1965: Fantastic Four 39 Kirby-Giacoia

Fantastic Four #116 (Pt 2) Sue from Fantastic Four #39

Fantastic Four 39 (1965) Kirby                     Fantastic Four 116 (1971) Buscema 

             Fantastic Four 39 (1965) Kirby              Fantastic Four 116 (1971) Buscema

Connections: Buscema likely looked to FF #39 for inspiration/reference, since Dr. Doom appears in both #39 and #116 (and you'll see some similar Doom shots in both issues). 

Also, Buscema's back view of Sue in #116 (the "a little afraid" panel) strongly reminded me of another image of Sue. I'll post it here next time.
