Yes! Any completely original item that isn’t interchangeable with another of the same item is non-fungible. So, an original piece of artwork like the Mona Lisa is non-fungible. An item of clothing is also non-fungible because it may be more valuable than another similar item because of who previously owned it or the condition it’s in. But neither of these things is inherently an NFT because a non-fungible token must be recorded on the blockchain. The blockchain functions as a transparent, immutable, permanent online ledger that keeps track of transactions. Therefore, what makes something an NFT is that it is both non-fungible and recorded on the blockchain.
