The above old 70-80s newspaper comic, written by Stan Lee himself, gave some idea of Spiderman's strength level. He was... okay, just street level. He cannot flip tanks. Kingpin and Daredevil can give him trouble. This is the Spiderman I remembered as a kid. So the question... when did Spiderman get so strong until he could throw buildings and stop trains?
