Auction # 2217 ARGENTINA: Special May auction

GJ.2768M/2769M, 1996 Self-adhesive stamps with logo of Correo Argentino WITH THE CONTROL MARKS in the borders at top and bottom produced by the automatic vending machine of the central post office of Mar del Plata. This machine was in use for a short period of time (it broke down often), less than 200 sets are known in this condition, the rest of the printing was sold manually and does have these typical marks in the borders. Excellent quality!
