A true mirror of sound : Bettini micro-phonograph, micro-diaphragms for phonograph and graphophone, Bettini celebrated "opera musical records" and autograph-records of world famous artists
A 1900 trade catalogue published in New York by the Bettini Phonograph Laboratory, selling micro-phonographs, diaphragms and recordings to phonograph buyers and dealers. The pictures show phonograph horns and reproducers in close, cropped views with price lines and product captions, giving a designer hard-edged shaded metal forms and vintage commercial typography to borrow.
