2018 letterpress calendar deluxe cover - Artist's proof
This is the deluxe edition front cover of the 2018 calendar designed by Tome Lane (Ginger Monkey). It's an artist proof.
An artist's proof is an impression of a print taken in the printmaking process to see the current printing state of a plate while the plate is being worked on by the artist. Some are cut, some are still uncut sheets with printing information.
