March of Comics was a long-running anthology comic book series published by Western Publishing. It was separate from their Gold Key Comics label, but often ran the same stories about the same licensed characters. Printed in a format that was smaller in both content and dimension than other comic books, it was not sold in stores, but given away at shoe and department stores.
488 issues were published from 1946 to 1982. Three of them featured The Jetsons.
