Tenite was one of the more popular plastics of the mid-20th century, used in any number of fishing lures ranging from the Rinehart Jinx to lures made by Millsite. Originating in 1932, it was hugely popular with commercial manufacturers of household items, but by 1960, when this ad was published, Tenite was on the way out. In an effort to stem the bleeding, the Tenite manufacturer in America (Eastman) began to advertise widely. This ad showed some of the lures still being made at that time, but within a decade Tenite had disappeared. The ad is a pretty one, though.
