It would be helpful to identify these women and provide information about their participation in racing or car building.
These are all pics of Kay Petre, who raced in England in the 1930s. The top pic is of a V12 Delage land-speed record car which had a second life at Brooklands. She lapped Brooklands' outer circuit @ 134mph in it. Only 15 men (and one other woman) lapped the outer circuit at over 130.
Not sure of the story on this one... But two hot rod ladies, one driving and the other maybe a crew chief, or maybe just a friend? Either way, awesome pic!
