Yes, it claims to be an ad from the December, 1922 issue of SCIENCE AND INVENTION, but it's actually from RADIO NEWS! The legend at the bottom and the accompanying article talk about how one goes about appealing to radio fans other than the geeks who get off on pieces of hardware. This is "what a real radio advertisement should look like -- an ad that can be understood by the merest tyro." Emphasis is on what you can get out of it: news, opera, jazz -- FREE!. Published in the editorial in the March, 1922 issue of RADIO NEWS.
