I've had a few of the old NHRA license plate frames with the "Happiness is a Low E.T." and "Land of NED" logos, but have never seen a metal NHRA keychain. Guessing this one is from the 1960s and still NOS, and a pretty good price, too. No affiliation whatsoever with seller, just thought it was cool.
