Friday’s ad is for a Canadian beer from Labatt’s. Labatt’s 50 Ale debuted in 1950 “to commemorate 50 years of partnership” and until 1979 was their best-selling beer. According to Labatt’s website:

John and Hugh Labatt, grandsons of founder John K. Labatt, launched Labatt 50 in 1950 to commemorate 50 years of partnership. The first light-tasting ale introduced in Canada, Labatt 50 was Canada’s best-selling beer until 1979 when, with the increasing popularity of lagers, it was surpassed by Labatt Blue. Labatt 50 is fermented using a special ale yeast, in use at Labatt since 1933. Specially-selected North American hops and a good balance of dryness, complemented by a fruity taste, provide Labatt 50 with all the distinguishing features of a true ale.

According to the ad copy, it was “Canada’s fastest growing ale because it has Spirit!” I’m not even sure what that means. The artwork looks typical of North American beer ads from the 1950s and so I suspect the ad is from that decade.
