"A Nickel Brings the Phonograph," New York Times, February 9, 1890.

ALBANY, Feb. 8. -- The Automatic Phonograph Exhibition Company of New-York City was incorporated in the Secretary of State's office today, with a capital stock of $1,000,000.   It is formed to manufacture, lease, use, and sell a nickel-in-the-slot machine, by means of which the dropping of a coin in the slot will operate a mechanism which will cause a phonograph or phonograph-graphophone to produce the sound recorded upon its cylinder, and after such reproduction cause the diaphragm to return to its original position.  The Trustees of the company are Felix Gottschalk, Willard L. Candee, Thomas T. Eckert, Jr., Richard W. Stevenson, Victor E. Burke, John E. Prague, and James Molinari.
