Have your teenaged friends over for a dance party, right in your own living room! Mom will feed the hungry crowd, and Dad will try to read his newspaper, but won't be able to resist tapping his toe to the music.

Special thanks to Radio material collector Steve Davis, for these images from his collection. [We Photoshopped them a bit to restore them to their original state.] Steve adds, "This Sears catalog was the first Sears radio-specific catalog, family and socially oriented. Earlier catalogs were electrical appliance catalogs, with radios in them." For more Radio material, try the MagazineArt.org site.
