This is the oldest signature 
(please post if you have a signature with an older address)
What's the meaning of the message? "1E9YwDtYf9R29ekNAfbV7MvB4LNv7v3fGa" is just an address with ~2mBTC. Could you sign another message? Preferably this one: "Today is December 4th, 2022, and I sign for topic #5421158". Also, money sent to "1NChfewU45oy7Dgn51HwkBFSixaTnyakfj" were paid in public key (block 1,018), so I'd expect a public key instead of an address. How did you end up with the address anyway (I've checked blockchair, and you're right; I just don't understand the point of this conversion).

Rather than signing dates, they should sign a hash of the block header that was mined 10 minutes ago. This proves it was impossible for a message to be signed by creating plenty of msgs or whatever. It's exciting seeing an early Bitcoin signature, thanks for the entertainment OneSignature.
Ya signing an address means nothing for timestamping. This address, while unused, could have been created at any time. Basically we have no idea if OneSignature actually can sign or if this is just a re-used signature from years ago. Also the OP is probably OneSignature, and this whole topic is just to show off that he found what he believes to be the oldest signature.
If the message that the signature signed does not include a recent blockhash, then it is worthless.
