According to promotional materials, nine CryptoPunks are being auctioned together in a single lot at the 21st Century Evening Sale on May 11.

And if you’re not quite ready to put up millions of dollars at auction, you can check out other CryptoPunks on Miami billboards in the near future, as part of a public art project called Pixelated.
