My 1969 Z/28 was bought out of Placke Chevrolet in St. Louis MO.
Today, I recieved a picture of the building and of Donald Placke.
The picture was titled "Mr. Hartman with Don Placke at Placke Chevrolet Company. Negative by Edward Goldberger, 1954".
I believe that Don Placke is still alive in St. Louis MO and that as of August 2012, he is 86 years old.
If this is correct, he was 28 when the picture was taken 58 years ago.
That means that Donald C Placke is the gentleman in the dark suit.

I believe that 1968RSZ28's car also came from Placke Chevrolet.
