I found these ads in The New Yorker. They're low-resolution, but readable and I found them interesting. I also included a couple of contemporary magazine columns. Also put in an ad from Pooley, a cabinet-maker for Atwater Kents. This caught my eye because they were making radio cabinet/bars in the middle of our Prohibition era.

The ads are chronologic:

Very Nice! I have a Model 30 in very rough shape, it's nice to see an add for it.

That's funny. I knew about radio bars during that era but it never occurred to me until you mentioned it that they were making them during prohibition! You gotta love the American spirit (no pun intended) !
