It's amazing how Superman can fly thru the air as fast as he does with an open box of corn flakes and not spill/lose any!! Not only are the boxes open (without top flaps), but they also appear to have no inner-bag in the box!!??!! But that's why they call him Superman!!

 

This "integrated" commercial appeared at the end of several episodes of "THE ADVENTURES OF SUPERMAN" during the 1955-'56 season.
