Human Torch sequence from FF #144:

Fantastic Four #144  (1974) Buckler

The breakdown:

The 144 panel (l.) is almost a mirror image of  1969's Fantastic Four 90 (r.) 

Fantastic Four 144 (1974) Buckler       Fantastic Four 81 (1968) Kirby

Fantastic Four 144 (1974) Buckler       Fantastic Four 99 (1970) Kirby                 

The #99 Kirby panel is an old reliable, rather generic Torch standard. For example, check it out in Fantastic Four #153.
