I also don't get it. An NFT is basically a small piece of text on the blockchain saying that you own the thing at a given URL. It doesn't mean you have copyright over the relevant intelectual property. There's nothing stopping the URL from returning a 404 at some point. And anyone can create an nft of anything, even if they don't actually own the intelectual property.

It really is as crazy as it sounds. The closest real world analogy I've seen is that it's like the people who sell deeds for plots of land on the Moon.

What's the URL for this particular NFT?

The info is linked to from here:

https://foundation.app/DisasterGirl/disaster-girl-25046

Here's the token:

https://etherscan.io/token/0x3b3ee1931dc30c1957379fac9aba94d...

What's burned into the blockchain is the URL of a JSON file which is hosted on IPFS:

https://ipfs.io/ipfs/QmYBvcJMaYFrUwhTRcbiHqFBoYPP54t4aBCnk1K...

That in turn points to the image, also hosted on IPFS:

https://ipfs.io/ipfs/QmeQ6c5HdnEDcheHmWuKWdwMHBBZg1eGpgV5h3H...

Here's the transaction which minted the token with the IPFS URL of the metadata as input:

https://etherscan.io/tx/0xccc3f7ee08307dd469af7c65c55e087edc...

As to NFTs themselves, you’ll have to understand Etherium smart contracts. This particular NFT is a Foundation NFT which implements the ERC-721 interface:

(Except the underlying contract actually appears to be https://docs.zeppelinos.org/docs/1.0.0/upgradeability_adminu... which I understand to be a contract that proxies its implantation. I’m not entirely clear how that works.)
