i just bought the limited edition look up the sky! The amazing story of superman from BB and it came with 5, 5x7 mini posters the fifth was the superman returns one which everyone has. I scanned them and uploaded them to kal-el.org for your viewing pleasure, my scanner isn't the best (canon canoscan N670U) i think i got it in 02 so i just bought today a new scanner and when it arrives i may reupload with better resolution and quality.
