I’ve used openclipart.org for a long time, I’ve always meant to submit something of my own. Because the site has an open submission policy, you can find some less-than-nice work on the site.
Finally, I have something good enough that I wanted to make it available to the world. Here’s the clip art page over at the site from which you can download the SVG or PNG of various sizes. If you like it, go on over there and “favorite” it.
