This deck is based card-for-card, image-for-image on the Aleister Crowley Thoth Tarot painted by Freida, Lady Harris. Serio is clearly a more professional artist than Lady Harris. The images here are more simplified and design-oriented than those of the original Thoth deck. But Lady Harris wins in the end for being sharper, more direct, and more evocative.
How the Liber T deck works best is in direct comparison with the Thoth deck. Examine the corresponding cards of each of the decks side-by-side to see what Serio did differently, what he emphasized, and what he downplayed. It is an instructive exercise that reveals much about both decks.

I wasn't sure what to expect from this Tarot deck, but as the owner of more than 185 various Tarots, I was prepared to be underwhelmed, despite the Italian publisher Lo Scarabeo's reputation. I was wrong. This is a beautiful, if odd looking deck. The style of the artwork takes some getting used to, but anyone familiar with the Crowley/Thoth decks will have no trouble reading with this deck. They possess a rich symbology, wonderful colours, and a somewhat eerie atmosphere. I'm not sorry I added this beguiling tarot deck to my collection. I highly commend it. In the game of Tarot, with this deck, LS has hit a 'homer!
