The Friday Cocktail - Santiago or Bacardi Cocktail?

Santiago or Bacardi Cocktail?, originally uploaded by Experiment 33.

From "The Calvert Party Encyclopedia" page 33 (1960)

Santiago
2 oz. light rum
2 dashes grenadine
4 dashes lime juice (which I interpreted as about 1/2 a lime)

I shook this up in my Boston shaker that uses one of those vintage glasses that has recipes on the side as the glass half. As I strained the drink, I noticed that the recipe on the glass for the Bacardi cocktail is the same with 1/2 tsp of sugar and only one dash of grenadine (and presumably Bacardi rum). Either way a tasty treat.
