This "Main Belting Co." circa 1912 Telephone Index is in wonderful condition and extremely scarce...it features a lovely Edwardian lady, her head gently reclining upon her cushioned chair as she speaks on her "Leviathan Belting" telephone. The cardboard is extremely sturdy and features an inserted metal rivet from where it would have been hung on a wall. It is copyrighted 1912 on the base. Alphabetized Index pages were never written in...this most likely came with the telephone! The Leviathan Belting Company was located in Boston, MA. There is a stain in the lower left corner that does not compromise the integrity and sturdiness of the cardboard. A truly rare and wonderful item!
