We would never dream of advocating smoking, but we will heartily recommend to you these posters by Octavian Mielu, which depict iconic superheroes entirely made up of smoke. It's probably better if you have a look rather than us trying to explain them to you.
So far, Mielu has designed images of Spider-Man, Batman, Hulk, Iron Man, Superman and The Joker.
We can't help but think it's something of an oversight that he hasn't yet designed one for Nightcrawler.
All the posters are available for purchase from Mielu's Etsy page, priced from £10.39. All come from a smoke-free home.
