The original Wirth Tarot was a deck of majors based on the Marseille Tarot, but with the addition of many more overt occult symbols. 

This edition, from US Games Systems, combines the Major Arcana of the original Wirth deck with a set of Minor Arcana. These Minor Arcana were specially created to complement the occult themes and imagery detailed in Oswald Wirth's Majors.

It is believed that Aleister Crowley worked with this deck.
