One of the earliest examples of ERC20 tokens (2016), wrapped inside an NFT, that can be unwrapped by burning the NFT. The artwork is a "tokenized" investigative report, released by the SEC, on TheDAO. See thedaotoken.eth.limo

TheDAO SEC Report NFT

The SEC issued an 18-page investigative report about TheDAO. The report concluded that, DAO Tokens, a Digital Asset, were securities. Each page of the pdf has been converted into bitmaps, then broken up into 100 tiles.

Each tile is minted as an NFT, with 1 original TheDAO token wrapped inside.

The NFT can be burned to unwrap 1 TheDAO token, which is a 16 decimal ERC20 token, created on Ethereum on Apr 30 2016.

This piece is from page 11, tile 1 (serial numbers start from 0)
