Poole Brothers

Poole Brothers was a publishing company founded in 1870 by George Amos and William H. Poole. George was previously a co-founder of Rand, McNally & Co. in 1868 and served as its first treasurer. He then left the organization to form Poole Brothers with William. The company was the largest printing house in the country that catered to transportation companies. According to The Inland Printer, "practically every railroad in the country" used Poole Brothers materials. Poole Brothers later expanded to print periodicals, including Advertising Age, Playboy, and the New England Journal of Medicine.
