I've posted about it years ago, but finally here are some photos of the GeeTeeO Tiger looking for some to drag race, I've read it was George Hurst in the costume sometimes

One of the most fun dragstrip promo events was a random spectator would be invited to beat the Tiger (normally one of the Royal Pontiac crew in a ridiculous striped getup) in a heads-up race with two Goats: one with a black panel, the other with a white panel.

It was called the In the "Beat the Tiger" match race.

In 1965 and 1966, at an NHRA National event, and if you had a winning ticket, you could actually "RACE" one of the Royal Pontiac "GeeTO Tigers" against the Mystery Tiger in a full 1/4 mile drag race.
