Here's a great photo of three punks hanging out in the Haga neighborhood in Göteborg, circa 1983. Notice the poster hanging in the window.
I had previously posted about this poster, but the salient link is no more. Here is the poster up close.
I don't know who took the photo. But thanks to SB for sharing it. Also, please no comments on how Haga is not actually "downtown" GBG. It's a formerly working-class neighborhood, now gentrified.
