RS274a, Wright’s Indian Vegetable Pills, Prancing Horse Cancel
William Wright was the vice-president of the North American College of Health, as well as the proprietor of Wright’s Indian Vegetable Pills during the 1840’s and 50’s. By the 1860’s he seems to have moved into private practice and left the proprietary medicine field. Edmund Ferrett was a music publisher in Philadelphia in the 1850’s, becoming an agent for Wright’s Indian Vegetable Pills by the early 1860’s. He ordered the Wright private die stamp in 1862. The Wright stamp was held up a bit by an argument over whether the word “proprietary” needed to be on it. The ruling was that it did not, and the stamp was first delivered in February of 1863. The last delivery was prior to October 1, 1880.
