Hey, Danish guy here.
It look like it's advertisement placed on scaffolding. Apparently the ad companies don't care about the laws/rules on advertisements on scaffolding, so the ad companies abuse that Copenhagen politicians haven't enforced the rules regarding those ads.
In Copenhagen, the major has very recently commented on it, calling it "The Wild West" (link to article, use DeepL or other tools for translations).
So usually it's not advertisements placed on a building itself, but on the scaffolds they use, when they're renovating buildings, or doing roof-work/repairs, etc.
