• Prince, George A.. Antique Piano Shop (AntiquePianoShop.com). "George A. Prince was by far one of the largest and most successful makers of organs and melodeons during the 19th Century era. Prince was established in Buffalo, NY in 1840, and they managed to remain highly successful throughout the Civil War era. At this time, the most common musical instrument in rural America was the small melodeon or parlor organ. Pianos were still too expensive for the average household at this time. In the decade after the Civil War, the piano began to become more and more popular in rural America, and by 1871 Prince went out of business as his melodeons and organs went out of fashion. These historical instruments are definitely of museum caliber today, and they deserve the finest restoration." See also: an advertisement in the 19th century, and an advertisement on New York Musical World (newspaper) in 1865.
