It looks like Grandma came up with this helpful radio hint from the December 1944 issue of Popular Mechanics. It was hard finding the stations on the dial of the midget set, so she made an alternative tuning dial. As the rest of the family helps, she cuts out the station listing from the local newspaper. There’s a bottle of glue on the table next to her, and Junior is bringing the set. They’re going to glue the station listing to the dial, and then draw lines pointing to each station’s spot on the dial.
