Here's a great collection of fictional magazine cover art from Ridley Scott's classic sci-fi film Blade Runner. The art was created by production illustrator Tom Southwell in 1980-1981 and appeared in the background of the film on a magazine stand in the city streets.
It's so awesome that after all of these years we can still come across cool stuff we've never really seen from these classic movies that we've come to love.
