I finally got to see this piece for the first time the other day. It's in Central Vally High School just outside Spokane, WA. Every year they have a contest among the seniors to design a class tile. I then reproduce the design on an 8" x 8" tile. I've done every year since 2005, 14 in all so far. Here's the last two years. The 2019 one was a real pain to duplicate.
