This auction is for a pair of vintage 1997 Z Z Top concert "cheap sunglasses."  These were not for sale - they are promo items.  Each stem has the Z Z Top logo in white on the side.  If you've been looking for a pair of these for a long time, now is your chance to own your own real pair!  There are many more pairs on Ebay, but this pair is the least expensive.  ---AND--- they come with a FREE pair of black sunglasses from 93.3 KDKB radio station in Phoenix, AZ.  This rock station is now history.....it's an alternative station.  But when is was KDKB - it ROCKED Arizona!
