I was just at the cinema and took/stole a avatar 27" * 40" big poster. I had to open a glass monter with my multi-tool to get it totally worth it :)
I am a bit disappointed cause here in Sweden there are enormous
commercial posters by the buss stops. Like 2 meters high and 1.4 meter wide, bigger then a normal human for you non metric users. All you need to take them out is a multi-tool, it's only two screws. But the avatar posters are already replaced, so thats a bummer for me that i did not think of that sooner.
