Butt Band

This weird old postcard from Germany is undated, but seems to be about a hundred years old. Weird Vintage has some information about the joke.

Apparently this is some fancy wordplay which makes a whole lot more sense when you’re in on the joke. User laurentbelkacem explained “About La Fanfare d'Écublens postcard - Écublens is a little town in Canton Vaud, Switzerland. The name of this town is pronounced in a way that in French sounds exactly, in this sentence, like “La Fanfare des culs blancs”, literaly “White butts brass band”.
