An American ebonite aid with a
metallic diaphragm first patented in 1895 by James Maloney. It is
engraved on top of the ear piece 'Globe Phone MFG Co Boston'
and this company was in business from 1907 through the 1920s. The
device is unusual in featuring a diaphragm and also because the
earpiece fits over the ear and is held in the hand. In excellent condition with no
cracks or chips and with
its original black ribbon strap.
