You can win one of them by just sharing any page or content from this website, to any social media, and sending the link of the place where it was shared back to me through my contact page or blog comment. Every month I choose one, two or three person, contact them back and send my prints free of charge.
To get the shared content link from Facebook, you click on the date and time of the content posted on your wall (just below you profile name), and it will lead you to the page only with the post shared. Copy the link and send to me. :)
