Just traced this for one of my own maps and decided to release it into the public domain:
The original is from a map made in 1583 by Antonio Millo.
Hope the colors are OK; I am colorblind so I can’t be sure (although I did grab them off of the original).
You can use this for whatever you want, no credit or anything needed (but of course appreciated; also if you let me know what you use it for I’d love to take a look).
You can download an SVG version at OpenClipart or the Cartographers’ Guild.
