Pair of early Telephone Books. Resemble somewhat of a Catalog but not quite. The Black one is entitled "The Rural Telephone" and was issued by the North Electric Co., Cleveland, Ohio. Total of 29 pages encompassing all you need to know abou the early Telephone and it's history. Photos and diagrams throughout. Measures about 7 5/8 x 9" Overall very good condition. A couple of the pages were neatly taped along the inner edge. The Red Book issued by the Sterling Electric Co., LaFayette, Ind. is focused on Switchboards. Total of 15 pages with literature as well as photos throughout. Measures about 5 1/2 x 9" Some tattering along the outside edges and some red marking to the inside cover page as shown in the photo. I'm guessing Books are from the very early 1900's era. If you collect early Telephone items would make a nice addition to your collection. Buyer to pay $4.50 for shipping & insurance within the U.S.
