Featuring good ole Uncle $at, these unique and 'easter egg' filled bills are my parody on today's paper fiat structure. In honor of 21 million Bitcoin, there will be 21 of these created. Once all 21 become owned, I will begin taking bids on the back as well, however, there will only be ONE back. Only one lucky collector will be able to own both. The winner will have the choice of either keeping the 2 seperate mints, or I will also mint the 3d rotating 360 file, or a 'side by side' version displaying both front and back in exchange for the recipient's individual pieces. Both old front and back copies would be burned, leaving only one of the two combined display versions, (and 20 front owners ofc) and a unique item for the lucky owner of both prior mints. Good luck!
