I made these back in the day. The idea was that you could print them out and have them along while dissecting bird necks, so you could draw on the muscles. It’s basically one drawing of an ostrich vertebra, morphed in GIMP and stacked to simulate articulation. All of the ones in this post show the vertebrae in left lateral view. If you need right views, flip ’em in GIMP or heck, I think even Windows Explorer will do that for you.

Not always solemnly.
