Sir Marshall Publishing, founded in 2004. Is a publishing house that produces skateboard books. Guenter Mokulys, the 11-time world champion, has been writing skateboard books since 1987. I was inspired by Rodney Mullen. The idea of capturing these quick trick movements in pictures. This makes it easier to understand and learn the trick. And that enabled me to improve my skateboarding a lot. And if I can learn it that way, others can too. That's how the first German-language skateboard book, "Freestyle Skateboarding," was published in 1987 by a publisher in Münster. More books were published. Until I founded my own publishing house and am now writing more books through this publisher. Skateboarding learning books for all ages, for all skateboarding disciplines. In German, English. Books available worldwide.
