The Todd Protectograph iHorn is made from a Todd Protectograph manufactured in the 1930s. The G.W. Todd Company was established in 1899 located in Rochester, New York.
By 1916, the company was known as the Todd Protectograph Co. In 1910, they reportedly claimed that 85,000 Protectographs were in use in businesses (e.g. banks and large companies). The devices were meant to prevent unauthorized alteration of business cheques, using an impression made by the machine that was difficult to alter. The characters were "shredded" into the paper and pressure was used to force ink into the shreds. The Todd Protectograph iHorn is the real deal. So protect yourself.
