NEW YORK SEMI-WEEKLY TRIBUNE, March 22, 1878

• Inventor Thomas A. Edison
• Phonograph invention explained

Page 4 has a nice article: "Explaining The Phonograph" "Ladies' Day at the Telephone Office". The report includes in part: "...The exhibition of Professor Edison's phonograph has lately attracted so many spectators...Mr. Applebaugh seated himself by the phonograph & for three hours devoted himself to experiments & explanations...". Then much detail on how his invention operates. 
Sixteen pages, some damp staining to the top quadrant, 12 by 17 inches, good condition.

Background: The March 22, 1878 issue of the New York Semi-Weekly Tribune represents an exceptionally rare and historically significant artifact of 19th-century technological journalism, as it captures the immediate public dawn of audio recording just five weeks after Thomas Edison secured his original patent for the phonograph on February 19, 1878. What makes this specific 16-page issue particularly notable is its detailed, front-row reportage on Page 4 featuring two landmark articles: "Explaining The Phonograph," which provides an intimate, technical breakdown of Mr. Applebaugh spending three continuous hours conducting experiments on the tinfoil cylinder machine for astonished spectators, and "Ladies' Day at the Telephone Office," highlighting the gendered social dynamics surrounding early telecommunication exhibitions. Because semi-weekly regional editions of major newspapers had much smaller press runs than their daily counterparts and were often discarded, surviving complete 16-page copies containing first-hand press accounts of Edison's early live demonstrations are exceedingly scarce, offering collectors and historians an unvarnished window into the exact moment mechanical sound reproduction shifted from speculative science to a mind-bending reality.
