My first exposure to “comic book art” wasn’t in comics, but from the syndicated Space Angel cartoon series on TV.
Alex Toth (pronounced with “toe”) was the artist behind Space Angel. Toth hired Doug Wildey to help produce the series, and Wildey in turn hired Toth to help him with Hanna-Barbera’s Jonny Quest. After Quest, Toth designed H-B’s less ambitious animated series, Space Ghost.
I loved this stuff when I was a kid, and I still love it. Space Angel had a 6-page promotion in the children’s magazine Jack and Jill.
I borrowed those scans from a Facebook post by author Ken Quattro, who wrote Invisible Men, a history of Black comic book creators.
