The US is relatively new, so I had to search for some classics. Fortunately I found a few.
An ultimate classic: the 1963 Covette with a split rear window, the only year for that design.
The Golden Dome of the University of Notre Dame, built in the 1870's.
The bottom of an antique green bowl, origins unknown.
I am having problems with my antique (but not classic) computer and must delay my visits to your pictures which I am anxious to see despite periodic crashes.
