I know you want an original poster. But as far as I know, they were only available folded. I have one at home, but unfortunately only one. Alternatively, you could have a poster in the size DIN A1 (59.4 x 84.1 cm) made with the enclosed file (at "myposter.at" - with laminated matt) - it looks really good. The cost is approx. 39.00 euros. But there are always very good special offers.
