Congratulations on the great deal, the 14k gold braclet coming with it is an added bonus to be sure. It is a beauty!

Based on inflation; $375 price tag in 1970 is worth $2,717.28 in today's dollars!
So I'm wondering if there is a distinct difference between the 'Christian Dior' and just plain 'Dior' models?
