Adaptation of Leonardo Da Vinci’s Two Jugs sketch (c1490)
One of the pictorial puns in the Leonardo Da Vinci’s collection include jugs. Beneath the sketch are what look the letters p v o.
Some people believe that Leonardo wrote backwards / did mirror writing. I have added what that might look like using the online https://www.dcode.fr/mirror-writing tool.
Some artists back in that era used a form of code to maintain secrecy of their ideas. I think Leonardo had a combination of mirror writing and other code to maintain secrecy. Nowadays there is Intellectual Property Rights (IPR) to aid people who create.
The jugs are sketched on a piece of purple brolly fabric.
