There is no trace about clues given back in 2015 by Coin_artist.

Looks like there was retweet about Base6 and Baconian Cipher but can't find the tweets from 2015.

Does anyone know if we have to look at the picture as a painting (no digital editing) or if we should look at it like a photo of the painting (could have been edited).

Could we solve the puzzle by only looking at the painting in a gallery for example ? (still having a computer to compute the base conversion, sha256 etc...)

Thx !
