Thomas Holloway was based in England. Holloway's Pills and Ointment were introduced in the States in the 1850's. A private die stamp was ordered early in the tax period and first issued in April of 1863. In the early 1870's the company may have withdrawn from the American market, and the stamps were last delivered in September of 1870. When sale of the products was resumed in the US in 1879 general issue stamps were used.
1,451,459 of the Holloway stamps were issued in perforated form and 146,316 were delivered imperforate. All were printed on old paper.
