German web site Castlemagazine.de puts out a free, monthly magazine that is jam-packed with illustrations from various "Illustrators, artists (and) other creative nerds." Further, the PDF publication is available online via download or email subscription.
Each issue organizes the submitted images by artist, providing their contact details for use by prospective employers. Since the magazine is graphically dense and light on text, the inability to read German is no barrier to enjoyment. Users can find out more, subscribe or download past issues from Castlemagazine.de.
