About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

Known for his subtle sarcasm, Joe had grown weary of his callers' constant queries of, "Can you hear me now..?"

Preamplifier in microphone box

The box with the microphone on its side contained a three-tube preamplifier.

Not self contained

The microphone cable and headphone wires head off screen, which means the electronics are elsewhere. No doubt a unit of this type would be useful at political conventions, inaugurations, etc. Basically, a telephoto lens for radio.

Here's a shot of a similar NBC device at the 1932 Roosevelt convention.

Parabolic mic

The black box with the NBC logo is an RCA type 4A microphone, so that has to be a parabolic reflector. Pretty sophisticated for 1931. The man's headphones are another clue.
