The Georgetown Loop Railroad got its name from this:
The post card was published by the H.H. Tammen Company, a novelty dealer and important publisher of national view-cards and Western themes in continuous tone and halftone lithography. Their logo does not appear on all their cards but other graphic elements often remain the same. H. H. Tammen (1856-1924) Harry Heye Tammen was born in Baltimore, Maryland on March 6, 1856, the son of a German immigrant pharmacist. He attended Knapps Academy in Baltimore, then worked in Philadelphia before moving to Denver in 1880. With his partner Charles A. Stuart he worked as a Denver bartender in 1880, and in 1881 they established the firm of H.H. Tammen & Co. (which in 1896 became the H.H. Tammen Curio Co., with partners Carl Litzenberger and Joseph Cox) in Denver, Colorado. Deeply interested in the study of mineralogy, he published a promotional journal called Western Echoes magazine, "Devoted to Mineralogy, Natural History, Botany, &c. &c." Volume 1 number 1 is copyrighted 1882. In 1895 Tammen formed a partnership with F.G. Bonfils (whom he had met at the Chicago World's Fair) and they became co-owners and co-editors of the Denver Post. Their publishing business flourished, and Tammen's business successes made him a wealthy man. In 1917 Buffalo Bill Cody happened to die while in Denver, and Tammen (one of the city's biggest boosters) offered Cody's widow $10,000 if she would allow Cody to be buried in Denver; she accepted, and the ensuing funeral procession drew 50,000 people. He established the H.H. Tammen Trust in 1924, providing essential health care for children of families who cannot afford to pay. Tammen died July 19, 1924. The H.H. Tammen Curio Co. was in business until 1953, and possibly as late as 1962.
