Are there jpeg artifacts, or am I hallucinating?

Anyway, these are actual bookmarks that you can buy for 300 yen each. Can't seem to track down the 300 dpi version (which would be suitable for printing and let you make some of these on your own, if you aren't able to purchase them due to location). I'd imagine the artist didn't upload one. If someone does stumble upon a hi-res version of this, however...

Do want.

I would like to have an Eiki bookmark. Mostly because the phrase on it is badass.
