These all all take their titles from the "sound effects" that they include. The first two (if not the third) are based on images from All American Men of War, published by DC comics. Whaam!, the best known of them and probably Lichtenstein's most iconic work, depicts a fighter aircraft firing a rocket into an enemy plane, with a red and yellow explosion graphic.
Drowning Girl is also known as Secret Hearts or I Don't Care! I'd Rather Sink – the last title from the words that appear in a speech bubble.
