I’d be angry if Leonardo da Vinci had been given credit for work that’s not his because it’s not fair to someone that worked really hard on it if he just steals it. However, I do not believe this because I understand that Leonardo da Vinci has potential and all his products were handcrafted by himself. Nothing should be done because it’s been proven his work is his.
The form of printing which used stone press on which areas are made receptive to ink is known as : D. Lithography
in this technique, the substance that is use for the painting does not necessarily have to be ink, but it does have to got greasy texture to it
hope this helps
