I've had an interest in the art for a while now. My collection of unusual artifacts includes a crystal ball/tarot deck, used for many years by a professional fortune teller.
This could become an interesting side venture - I will update you with my progress.

The first 78 card deck was discovered in Italy, dating back to the 15th century. Originally a parlor game enjoyed by nobles (the cards depicted family members, tailored to each owner) the art of fortune telling developed soon after.
