"HooDoo" Amplex?

I just uploaded a neat article complete with decent image concerning driver Joe Horan's May 24, 1911 practice wreck at the Indianapolis Motor Speedway. The car he drove was the Amplex #12, the same machine replacement driver Art Greiner would also crash early in the first Indianapolis 500. That accident produced the race's only fatal injury, which involved riding mechanic Samuel Dickson (pictured).
