Friday’s ad is for Heineken, from 1978. In the later 1970s, Heineken embarked on a series of ads with the tagline “Heineken Refreshes the Parts Other Beers Cannot Reach.” Many of the ads were in a sequential panel, or comic strip, format and they were intended to be humorous.

In this ad, a two-panel format, a caterpillar is holding a mug of Heineken awkwardly as we appears to walk. But after downing the beer, he’s transformed into a beautiful butterfly. Curiously, he still has some caterpillar legs though so maybe the transformation isn’t complete yet. I’m sure another beer should do the trick.
