The picture is of the original Maid-Rite in Muscatine, Iowa, where I was born. I took pictures there in 2007. The Angel brothers started this restaurant in 1926. Those of you with recipes that call for ketchup in the recipe have got a FAKE recipe. Maid-Rite has NEVER added ketchup to their meat for their classic burger while cooking it. The secret is twice-ground ground beef (probably the cheapest you can find). The meat is very, very fine.
