All buyers of The Rarest Sets book receive the Counterparty asset RARESTSETS as a proof of purchase. A special sub-asset was created for the winners of the first 5 mints of the book called RARESTSETS.AUCTIONWINNER. Buyers of both The Rarest Sets and The Encyclopaedia Pepetannica also receive RARITYHOLDER as a token of my appreciation. The image used for RARITYHOLDER was created by psyfrogger.
