Caesar's, 1950s

Notes from the collector: The cover page says "Home of the Original Caesar's Salad" If this is correct then this is a treasure. I have no idea where I got this menu nor the date. But it looks like it is from somewhere around the fifties or the sixties. Maybe someone can throw some light on both the origin and the date. The menu is certainly balanced and lively with a wide variety of wines, but none from the northern neighbor.
