I guess I misremembered, but it's the same recipe as the other three. The earliest I can find it in my collection is in the 1934 Boothby which is where I must have found it circa 2007. EUVS has it a year earlier in the 1933 Hollywood Cocktails (third printing, they don't have the other two printings scanned in).
Not insulted in the slightest, and I'm giving tribute to Phil for teaching me one of the tricks that I used. However, the Cantiflas recipe was probably garnered from a menu and Simon admits that he is guessing the recipe since Phil never released it to get published formally, so I never knew that it existed. And I have to imagine that Simon gave it a college try of searching the web for "Cantiflas mezcal cocktail" or similar to get at the old Mayahuel recipe and found mine.
