This 1953 print advertisement for the National Motor Bearing Company Oil & Grease Seals has a black and white art illustration by Arthur Radebaugh of a machine that doesn’t look unlike a termite in a tunnel with the headline, “When mole-like machines ‘melt’ tunnels through mountains… precision National Oil Seals will protect their performance”.

“Incredible machines may someday burn their way under cities and rivers, through mountain ranges—fusing earth and rock into everlasting tunnels for irrigation, railroads, or auto expressways. Such machines will be marvels of complexity. Yet, like today’s equipment, their performance will depend on oil seals and O-Rings.”
This is a 67 yr. old original vintage ad removed from a 1953 publication and is not a reproduction of any kind.
