and I just now realized that this piece very well might be the first (and only) item that is both real physical bitcoin AND legal tender?
I definitely might be mistaken, but I simply can't think of any other art piece/collectible that would qualify..?
Kialara released "thug life" in 2017. Off the top of my head that's the only one I can think of.
