an advertisement from one of histories greatest scammers E J Pennington

that is a remarkable historical ad right there, and the last line about an Armor-plated Motor Machine Gun Carriage, referred to this

E J Pennigton was an inventor and promoter of many mechanical devices, including airships, motorcycles, and automobiles. In addition to motor vehicles, he applied for and received patents for Stirling engines, ignition systems, planing machines, and pulleys.

He often promoted his inventions with grandiose and spurious claims, which would become a hallmark of his entrepreneurial schemes. Frequently he collected financial backing for his business ventures, but rarely (if ever) did his investors ever collect any dividends from his projects. He was regarded by many as a fraud on account of his unproven claims and business practices, yet he never spent any time in prison as a result of these accusations.

Pennington is probably best known today for his pioneering motorcycles. He is sometimes credited with having invented the word "motorcycle"; he used the term as early as 1893. Pennington built and demonstrated his original motorcycle design in Milwaukee in 1895.
