Tuesday’s ad is for the London brand Barclay’s Lager. Getty Images claims it’s from around 1900 but the artist, Tom Purvis, was born in 1888 meaning he’d have been 12 then, so it seems more likely it was actually later. The ad reminds me a bit of the Blues Brothers movie, the scene at the bar where the bartenders tells the band they have both kinds of music, country and western. They serve both kinds of lager, “Light or Dark.”
