yellow science mania

Cut-paper collage postcard on which I played around with the color yellow. Background is the surface of the sun. Giant lifting big yellow planet is from a 1930s-era cover of Astounding magazine. I don't know what's in the Erlenmeyer flask, nor do I know what singer that is. The labeled diagram in the upper part of the image is of a nuclear reactor.

Here's a question for you...There are two American comic strips quoted in this collage. One is easy to get: on the right is Dagwood with his sandwich makings, from the strip "Blondie." What's the other one?
