Baltimore consumer experience and creative agency Harvey has released a series of limited-edition non-fungible tokens (NFTs) to support the National Aquarium’s conservation mission. As part of the agency’s newly created holiday, Hark Week, the NFTs feature mashups of shark and holiday memes.

As defined by Crypto platform Coinbase, NFTs are “a special kind of cryptoasset in which each token is unique — as opposed to “fungible” assets like Bitcoin and dollar bills, which are all worth exactly the same amount.” NFT are unique, allowing them to be used to verify ownership of digital assets like artworks, recordings, and a wide range of other virtual assets.”

Hark Week uses pop artwork created by the agency’s Senior Art Director, Rick Bowman to capture the fun of the holidays and the allure of the sea’s apex predator.

“The last two years have really bitten the big one thanks to pandemics and politics,” said Harvey President and CEO Matt McDermott. “We figured, why not come up with a new holiday that uses what’s relevant in tech now to do a little good.”

Purchase of each NFT includes not only exclusive ownership of the digital asset but also unlocks additional perks, including a free Ocean Ambassador membership from the National Aquarium and a gift bag from Harvey featuring products from clients of past and present: Flying Dog Brewery, Michele’s Granola, Goetze candies, and more. The four NFTs are available for sale now through Christmas Eve.
