6 Haunted Days

Yea, it's just a transformational deck of playing cards. It is beyond gorgeous though!! Just breathtaking images with delightful ryhmes.

It was published in the 90's and it had a contest to find and answer the riddle hidden within the rhymes for like $10,000! It was reprinted a couple years ago, I don't think it's OOP. Sure doesn't look it according to Amazon. I got mine at at local shop, and she had just ordered it from a distributor.
