Roland Martin sunglasses

Sitting here watching an old (prob. made around 86 or 87) episode of Martin's show.  Funny to see a pro fisherman fishing out of an aluminum Bass Tracker.

Anywho, I wish they still made those old square sunglasses.  I've looked everywhere for the last several years without success.  I remember two of my uncles had those glasses and I loved the way they looked and felt.

Anyone know of any places that still sell these?  Not listed on his website, so I'm probably out of luck.
