FINALLY!
I had been looking for this.
When I bought my seal, they offered the free electronic DXF version. When I saw it, I was disappointed because it looked like they used the stamp, scanned it into their computer, and then converted the raster graphic to vector form! It looked like crap but it does look like the "real-world" stamp. I saw one, where I used to work, that was perfect like the one shown above.
Oh, and FYI: My stamp must have been hand-made with a potato or something because the star is not centered, among other issues.
