This all rings true but the additional appeal is the investment, rarity, and exclusivity....the longer and longer time goes by the more and more the vintage frames will be falling by the wayside, damage, breaking, getting tossed, lost, etc... so they do nothing but appreciate with time if maintained and taken care of. They are wearable, tangible, investments, and what is being produced by Safilo and Luxxotica is plastic they call acetate, designer frames that cost less then 2 bucks to make, no detailing or craftsmanship, no makers marks or designer quirks that bring value, It just a bunch of glasses made of the same fucking materials just designed differently....the guccis may cost you 300 the SLPs maybe 350, but the Anne Kleins will only run ya 20 and they all share the same thing in common, they possess the same quality and lack any form of true craftsmanship. They're garbage and some of the biggest fucking rackets in the industry. It killed me when Oliver Peoples went that route, I still love the frames but i truly thought they would hold out and stay true and keep production in Japan...but I guess everyone has their price....the only current Sunglass company I would vouch 100% for and are true works of art, are Dita. Those glasses are fucking gorgeous are amazingly crafted...but in general, the industry has sold out and is dying...just another factor adding to the value of vintage.
