University of Pennsylvania, Penn or UPenn, is a private, Ivy League university located in Philadelphia and founded by Benjamin Franklin in 1740. Penn is one of 14 founding members of the Association of American Universities and one of the nine original colonial colleges.
The Detroit Publishing Company was one of the largest American publishers of postcards and photographic views during the early decades of the 20th century. The Detroit Photographic Company originated in 1898 to promote a new color printing process in the United States and to capitalize on the public's interest in sending inexpensive pictorial greetings. In 1905 the firm became the Detroit Publishing Company, continuing to use the trade name "Phostint" for its patented color reproduction process. Western landscape photographer William Henry Jackson was long associated with the firm, bringing his and other photographers' negatives to the image stock published by the company. Photographers' names are not associated with individual postcard images, although art reproductions and illustration series are credited. Diminishing sales and rising competition from rival firms sent the Detroit Publishing Company into receivership in 1924, and its assets were finally liquidated in 1932.
