(Old Books, Early 20th Century Books, Telephones, Electricity, Magnetism, Diagrams, AT&T).

The Application of Electricity and Magnetism to Transmission in the Telephone Plant.
Published 1923, United States by the American Telephone & Telegraph Company (AT&T).
5 volumes, each c. 50-100 pages. Text in English. Profusely illustrated throughout with countless diagrams and drawings.

Publisher's paper wrappers, original staples (still clean and unrusted).

Set is physically old and shows some signs of handling and time. 

Bindings gently age worn, yet overall fresh, attractive individually as well as a set.

Text block paper is gently toned, internally still well preserved, tight, sound. 

Clean set which has seemingly sat largely untouched for almost 100 years. Retains the ephemeral, loosely affixed mimeographed typewriter errata leaf prior to the title page of the first volume.

Still attractive on the shelf. Set displays a pleasing and unique age patina and is in nice antiquarian condition, any age flaws easy to overlook or forgive. 

Please review photos for more detail and our best attempt to convey how this uncommon/ scarce early telephone-related set survives.

Books Measure c. 8" H x 5" W.
