Vintage coupon, K-9 DOG FOOD Bishop Mills Martinsburg W. Va., also a postcard, in n-mint+ unused new old stock condition. Nice clean coupon. Size is 3 1/2" x 7". Scans show both sides. The black background is so all the edges can be seen and is not part of the coupon itself. NOTE: All of the advertising items I have listed are guaranteed to be 100% authentic originals. They are all clean and ready for display. Thank you for your purchase I appreciate it.
