John S. Cotton & Co., Philadelphia

I have no information about this firm. It was at 409 Chestnut and it was publishing as early as 1858.

In 1860 this company reprinted the four twelve volume series that Philadelphia publisher Keller and Bright had published in 1856.

The formats are the same as Keller & Bright's and R. F. Simpson's. Both the latter publishers were Philadelphia firms.
