I am looking to download some set/s of tarot cards in order to print them. This needs to be from a free site. Grayscale cards are also acceptable. It would be great if the images are designed specially for printing on A4, as then I could print sheets and cut them up.
The most popular version in the English speaking world is the Rider-Waite Tarot cards. These were published in the early 20th century.
This site has The Pictorial Key to the Tarot that contains B/W images of the Tarot cards (clicking those opens fair quality scans in color). The book and the images predate U.S. copyright laws.
These images here are the best high quality scans I have found of these old images.
