Vintage 3 3/4" by 2 3/8" card stock coupon/card that was redeemable for a free six pack of Coca Cola in bottles. It features a colorful illustration of an early 1960s carton of Coke bottles. This is unused 1960s stock found in an old Coca Cola plant. These were given away with purchases and the customer was instructed to save them to redeem five for a free six pack. Each says "This is our way of saying thanks for coming...and thanks for coming back." Like new, glossy condition !
