Thunder Box!

This rather tawdry excrescence protrudes from 86, rue Potagère - two doors up from me - must have passed it thousands of times without it really registering.

Now that I'm cursed blessed with blipster's eyes, I've finally recognized it for what it is... A genuine thunder box!!

Good grief, you wouldn't want to hang around it there when the temperature descends below -10° C...
