The artist here is Ernie Colon, not entirely unknown to the mainstream/superhero comics market by this point – and who is still producing comics to this day. The approach presented here – two separate but related stories on the same page, in different colors – is quite original and very distinctive. I also really enjoy the second panel, where it looks like Hitler is yelling at the men in the boat.
