Decks of high artistic merit

Spectre Made Flesh

Some of the Italian decks from the 1800s have fantastic artwork, IMO, with their intricate details and mystical vintage look.

Photo collage/digital artwork isn't usually my taste for Tarot decks, but I own this one because the artwork is so classy looking and darkly dignified.

Wow, four pages and no mention of LLewellyn? It's "just" watercolors, but I think it's gorgeous, especially the majors.

I thought about including it but the card (image) size makes it harder to appreciate for some. I'm glad you gave it mention. The majors ARE glorious :)
