At the end of 2004 was a poster magazine by the publisher Attic Futura released. It was the only issue of this kind. 

I remember how I saw the first Winx Club magazine and this poster magazine in store. I would have loved to have both but I was too shy to ask if I could have both so I decided to only get the Winx Club magazine. My back then best friend got the poster magazine on the same and so I was kind of having it. She borrowed me the poster magazine so I could trace all the posters onto tracing paper.
Years later I was so lucky to find a well preserved edition on ebay.
