I had to play through the game until I came across one of the posters on a wall, and then used my digital camera to take a photo of the screen (I was playing on XBox through a projector, and didn't have a capture card at the time). The 'Courage Today, Victory Tomorrow' in-game posters always excited me and so I decided that I would try recreating the in-game poster in great detail and large enough that it could become a wall feature. Being a huge fan of Fallout 3, I wanted to hang some of the retro-futuristic propaganda art in my office but, alas, couldn't find any.
This project was actually a bit of a nightmare.
