Color: Printed Color
A. The Duston Radio Broadcast Map [with] Radio Log and Call Book, by Merle Duston, published 1924 (21.0 x 14.4"). This map of the United States is divided into both time zones and radio districts. All radio stations of 100 watts or more are identified along with their corresponding call letters. Accompanied by a 21 page listing of radio stations, log instructions, and empty log pages. Duston was a radio engineer who wrote a number of books on radios in the 1920s. He is probably best known as the inventor of the photoelectric paper tape recorder in 1932. The map does not appear in OCLC. Condition: The map is very good with several small fold separations and an edge chip confined to the left blank margin. Text is very good and separated from the paper wrappers, which have light wear and soiling.
B. Radio Map of United States and Canada, by L.L. Poates, dated 1923 (29.9 x 19.3"). A larger map of the United States divided by time zone and radio district in green overprinting. Radio stations and their corresponding call letters are identified in red overprinting. Only two stations appear in Nevada and New Mexico. No copies of this 1923 version located in OCLC. Condition: There are a few tiny tears and separations resulting in minute loss of image at the fold junctions. There is some light show through of adhesive at lower center from where the map was previously glued onto paper wrappers.
Issued folding. See description above.
