If you google 'vintage disney posters' you will see images of retro flyers on a blog that features the People Mover, Skyway, and Space Mountain among others. I read somewhere that they were created by a graphic artist that was subsequently hired by Disney to work on like projects for them.

Has anyone seen anything like this in the parks? I am specifically looking for WDW retro posters. I will be there in a couple weeks and would love to bring some home.
