Oh sorry, hemera - I thought the 1001 nights was a pre-trim scan. I see now what you mean. When I look closer they look like magic carpet designs, and I get the looking through a window or portal effect. The black arched borders on my Hallowquest deck have that effect too.
I might look up the Irwin companion to the Nights. The Haddawy translation takes no prisoners - any versions of the stories I had read before (years ago) were Victorian sanitised versions written in antiquated language. There are quite a few X-rated activities in this translation
and the style is clear and natural and the dialogue very realistic. The stories really come alive off the page.
Maybe I should look up the deck too. It looks nice. Hmmm, now where did I put that credit card.
