A Dash of Bitters
A weblog detailing cocktails, spirits, liqueurs, barware, bars, and bitters. Maintained by Michael Dietsch, a writer and hobbyist mixer in Brooklyn.
Lots of cool ads from the same year (1935) for rums and other spirits (and things not alcohol related) in the Florida Cocktail Book (Florida Bar in Cuba):
