John Atzbach spent most of his life hunting and selling the works of Carl Faberge. Needless to say, he knows the value of artwork along with the attention to detail it requires. That is what captured his attention about Carroll Shelby's creations. Admiring all things Shelby with the same respect as Faberge, he amassed a collection that will leave you speechless. That's why you must tune in at 4 p.m. ET, as Mecum will preview this unprecedented Shelby collection on NBCSN.

The press release mentions priceless examples, such as: a 1965 GT350 R-Model, a Paxton-supercharged 1965 GT350 Prototype, the first production 1966 and 1967 GT350s by serial number and the first 1966 GT350 convertible of just four produced.
