Four Color #223

In "Too Fit to Fit," Carl Barks delivers a delightfully odd adventure as Donald Duck, now a museum janitor, stumbles upon ancient Inca "blocks" that turn out to be square eggs. When the rest of a scientific expedition falls ill, Donald and the nephews press on into the Andes, where they encounter a mysterious people who speak with Southern accents and live entirely on these peculiar eggs. The story, written and illustrated by Carl Barks with full creative control from cover to color, showcases his signature blend of whimsy and adventure in a 1949 comic that remains a standout in the Four Color series.
