Let us ignore the existence of Buck Duck entirely. The cheapness of the work, the obvious Donald thievery, the odious small rough-talking kid - these are "Golden Age" comics at their worst, slop shoveled out for kiddies who'd buy anything. Once.
Consider, instead, the Distant City. For decades, comic books have set many urban tales in a strange location outside the city itself. It has the trappings of dense urban life - sidewalks, streets, buildings - but the rest of the city is off in the far distance, an almost spectral presence, indicated by a silouette of towers.
What's across the street from Buck Duck's location here? NOTHING. There is nothing there. The city stops, and miles away rises another.
This site will explore a few examples over the ages.
