Scarce separately published map of Philadelphia, published to commemorate the 100th anniversary of the birth of the US
While the title refers to Wade's New Map of Philadelphia, this map was clearly printed by SA Mitchell Jr.
The map was published for the 1876 Philadelphia International Exposition, celebrating the centennial of the United States.
Around the edges of the map are engravings of 8 of the major exposition buildings. The center shows the plan for the city of Philadelphia.
Samuel Augustus Mitchell Jr. inherited the Mitchell Company from his father in 1860. For over thirty years, the company had specialized in the production of school atlases and wall maps of America. They were one of the pioneers on engraving on steel plates. In 1860, Samuel Jr. released the New General Atlas, which had been compiled in house and replaced a previous atlas by Tanner. The elder Mitchell died in 1868 and Samuel Jr. continued the business until the 1890s. At its height, the Mitchell Company employed 250 people and sold 400,000 publications annually.
