Doug: Back on the 12th of November, Inkstained Wretch commented on the Eternals #1 post that Jack Kirby's art had declined noticeably over a rather short period of time. He said:
It is amazing to think this was only six years after Kirby was doing his
classic work on Fantastic Four, Thor and Captain America. His art on
those around 1969-70 was some of his best ever. What happened during his
tenure at DC that caused it to change as it did?
Doug: I think we can all for the most part agree with this assessment, and that brings us to today's question -- can you name other writers and artists smitten with a similar fate? For my money, "Exhibit A" has to be Don Heck. Just earlier this month he was in many a'commenter's list of favorite Captain America artists due in large part to his run on the Avengers in the early Kooky Quartet era. Yet, by the dawn of the Bronze Age all fluidity had left his figures and had been replaced by stiff characters that resembled cardboard cut-outs. His mid-70's work at DC on titles such as Wonder Woman, Teen Titans, and Batman Family is the stuff of anti-legend! I offer a couple of original art samples below. The first is from Avengers #17 (June 1965) and the latter is from Avengers #112 (June 1973).
