The Yankee Burger restaurant, 20 Frankfurt Gate was the location of two murals painted on opposite walls by Lenkiewicz in 1976. Each measured approx. 1.2m x 2.5m and continued the wild west theme of the restaurant.

Local press reports during October 1976 stated;

The murals, now almost completed, have however, turned several stomachs while waiting in eager anticipation of a succulent burger. Mr Lenkiewicz has introduced some of his gentlemen of the road to the gun play of the Old West by dressing them up as cowboys and adding a few dead bodies for authentic good measure. "People get a bit upset about the decapitated head and the corpse," said american owner John Desiderio. "The head is from the body of a North Califorian bandit. When they captured him they cut off his head and stuffed it in a glass jar of alcohol and had it exhibited in a museum in San Francisco, but it was destroyed at the time of the first earthquake." Then there is a corpse clutching a pair of Aces and a pair of eights. "The fingers are holding what is known as a 'dead man's hand' - and that's the cards Wild Bill Hickock was holding when he was shot in the back of the head. People say how can you have that in a restaurant, but they don't know the story. It isn't really that gory." There is another customer who has other ideas on the subject however. He always sits with his back to the mural.
