For your browsing and research pleasure - Dave Friedman was the official Shelby photographer as well as covering many types of racing through the years.
Racing pictures from 1958 through 1972. Mostly sports car racing with some Trans Am, Indy, F1 and a little NASCAR thrown in. There's a whole section devoted to Shelby American with behind the scenes type pictures.
The collection of photos is organized by year and broken down by event. Inside each event, though, the photos seem rather random.

I believe this collection has been referenced in different build threads but thought it might be handy to have in this section.
Enjoy!
