These 1939 advertisements might show more about marketing “angles” than the product itself. When something becomes, more or less, a commodity then efforts to sell a particular brand often emphasized an emotional but relatively unrelated topic to persuade the prospect to buy. This wasn’t a new technique in the 1930s but it became more widespread.
“In 1928, Adolph Schleicher, owner of Samson Tire and Rubber Company had a small factory in Compton, California but decided to move to a bigger location in East of Los Angeles. The factory in East Los Angeles became the largest manufacturing facility to the West of the Mississippi; it took 8 million dollars to create. This factory was modeled after the 7th century BC Assyrian Palace of King Sargon II, the wall surrounding the tire plant featured heraldic griffins and bas-reliefs of Babylonian princes.
“The Samson Tire Company only operated for a year and sold the factory to the US Tire Company [in 1930] due to effects of the Great Depression.”
