Artists that you would like to have made Tarot decks, but never did :(

devilkitty

Caspar David Friedrich.
 

Electric Maenad

Rebecca Guay
Charles Vess
Scott Hampton
Rich Burlew (artist / writer of Order of the Stick)

NB: All these people are still alive, so I suppose a deck from any of them would be a theoretical possibility. Just unlikely.
