That I know of, Meguiar's introduced the "Wooless Wonder" in 1965.
I think this is the year Gilligan's Island debuted.
I know its the year the Rolling Stones came out with, "I can't get no satisfaction", and the Beach Boys came out with, "Help me Rhonda".
Or, to put it into perspective, shortly after Ford introduced the first Mustang. (1964 1/2)
I have an orginal one in my collection. The foam is now disinigrating however,
