hello, i got a great friend who has been the official retailer, in a french ski resort, called Avoriaz, and he has found some limited editions and rarities he'd like to sell ; i took all his stuff to check what i wanted first for my collection, but i've found 2 sunglasses i didn't ever know.. so maybe someone here could tell me what models are they, how are they are (or not!), and if i'd better buy them (or not)
