Hmmm. I thought that was the first appearance, but then ran across this:
"Joe [Henning] teamed up with journalist OCee Ritch in the early '50s, contributing to a number of magazines including an appearance in Hop Up in 1953. But it was their rendering of "The Roadster," a Model T-bodied hot rod they claimed could be built for a dollar a pound, that put them on the map when it appeared in the May, 1955 issue of Rod & Custom. Throughout the rest of the decade they continued to push the boundaries of automotive design (and in some cases, auto industry patience) with their interesting, sometimes space age, often-outlandish re-styling ideas."
