@Banana Breath,
Joseph Ray Watkins - originator of Watkins Incorporated
The company was founded by J. R. Watkins in Plainview, Minnesota, who began selling liniment in 1868 door-to-door in the southeastern part of the state. A year after J.R. Watkins began selling liniment, he introduced the trial-mark bottle. Molded into the glass bottle, about one-third of the way down,[2] was a mark which showed how much of the product a customer could use and still get a refund. A label with the statement, “If not fully satisfied, your money cheerfully refunded,” also appeared on the bottle. The Watkins trial-mark is believed to be the first money-back guarantee[3] in America.
