The Whopper beat the Bigmac

Back when I was a kid my brother, sister , me and my friends used to walk up to Burgerking and get food. back in the 70's Burgerking had all type of fun promotions. One promotion had customers saying"The Whopper beat the Big mac" and you would get a Whopper free with the purchase of another Whopper. Well another promo was free Meadowlark Lemon posters with the purchase of food. I don't know how many of these posters I got but I got quite a few, I had forgotten about it until recently. Good times.......
