Here are some great photos from the Boy's Republic Steve McQueen Car Show which took place June 4, 2011. 

"Chad McQueen was there signing items, as was Matt Stone, the author of 'McQueen's Machines', who was signing copies of his book.  Also signing there was famous race driver Vic Elford and a handful of other men involved in the filming of McQueen's movie LeMans in 1970.  Chad also brought two of Steve's old Porsches, a grey 1969 911S and a black 1958 Speedster, both of which Chad still owns.  Both cars are also featured in Matt Stone's book."

Special thanks to Gary Decamp for the description and photos!
