A friend pointed out this [Charles] Dennis always appears in the lower-grade girlie magazines and his cartoons often look like roughs. I wonder if many of these were attempts at submitting to the top markets like New Yorker, Playboy, or Esquire and then selling sloppy seconds (or thirds, fourths, etc.) to lesser-known magazines.
