I started releasing free paper toys in 2007. Most of my paper toys are still available for free download through my website www.markozubak.com. SAMURAI is a paper toy from 2008 and was never released before in PDF format. When you purchase it, you'll get the proof of ownership on the blockchain, with exclusive access to pdf file containing it's visual code, which, in order to materialize, has to be printed, cut out and constructed.
