Blue Lobster Fishing
Norman Rockwell created a second April Fool cover for the Saturday Evening Post
. His first such cover, in 1943
, had been the magazine's most popular cover ever. Like its predecessor, the 1945 cover contained numerous "mistakes and incongruities" — 50 in all, according to Rockwell. However, the Post editors warned readers that the blue lobster didn't count as a mistake, noting that the "blue lobster is a rarity, but every once in a while one of them turns up in Maine waters."
