Eventually I hope to make all Major Arcana (and possibly all Minor Arcana) cards for this project.
The cards are lenticular, meaning that I've made a format where they can be printed out and have a special lens put on them so that you can see two different versions of the same card - the red "upright" card and the blue "reversed" card, depending on what angle you view them from.
Left: Upright
Middle: Reversed
Right: A lenticular version
