German government poly ad?
It's from the German Ministry of Economy and Energy. Translation: "Efficiency is conserving the energy. Not the warmth."
They look relaxed and happy. Who knows if the ad designers were thinking of polyamory specifically (can someone find them and ask?). But really, 10 or 20 years ago, would they have expected this image to connect the way it does now?
Thanks to TRNogger on reddit/r/polyamory for spotting this.
