A set of four different Christmas cards using silhouettes of many OCAL graphics with text in English and German. Options: green, red, more traditional and penguins. The font used is 'Great Vibes' (http://openfontlibrary.org/en/font/rebecca), licenced under the SIL Open Font Licence (http://scripts.sil.org/OFL), which allows to use it for any purpose with no requirements for a specific licence of the work in which it is used. I updated the SVG to have the original text below the picture, so it won't interfere with export to png, but OCAL did not update the png and pdf images accordingly. If you want to use it, best download the svg file itself.
