As you can see, it is the 12 animals of the Chinese zodiac. While cow is not an animal of the zodiac, if you look at how the artist positioned the Himotoshi (the little circles that are added as a callback to how the art-form originated) against the animal below it, it actually looks like a cow itself (the himotoshi being the eyes).This is best seen in the first picture. Sort of like a 13th animal suggesting the bovine material from which it is made in a very artistic (in my opinion) way. It is really nicely done.
If you need more photos let me know, but I tried to take a whole bunch so that you can see the intricate details that the artist was able to etch into it. I can't even imagine how many hours (not to mention the skill) that goes into producing a piece of artwork like this. Please let me know if you have any questions, and thank you for looking!
