Thanks guys! I have had a lot of great response to this idea.
For guys of my era when we were kids there was no screen to look at ,so we sat and stared at the speakers and memorized the tuning dial instead.Roy Rodgers,Gene Audrey,The Inner Sanctum etc...etc...Many wonderful hours spent in front of those old radios where the visual images were all in your head.(good training for future dioramists)We had very active imaginations in those days.
The same idea could be used using radios or TV cabinets from the 50's and 60's.Just think of the diorama that could be built into an old jukebox.
