Found a picture of Odin astride his horse Sleipnir, with Hugin and Munin on his sholders whilst visiting a web site maintained by Daniel McCoy. I have a soft spot for old simplistic images like this and tried to reproduce it as a wooden relief panel.
Apparently the image above has been taken from an Iron Age helment found in Sweden. I’ve copied it and tried to convert it to an SVG format so it can be re-scaled. Its stored here if you want to have a go yourself.
