Best viewed monospaced. The reader uses this layout exclusively. I've never seen it before, and can't find any references to what it might be called or how it is used. If anyone has any insights, please e-mail me at nuttincute@yahoo.com.

I haven't seen it, but I'm no expert and not well-travelled in the byways of fortune-tellers.

It looks like a capital "J" (with serifs), or a backwards "G".

Can you tell us any more? Like where did you see it, who the reader was, what kind of deck was used, how was it read - significator/no-significator, other special cards or combinations, etc., what various positions meant, those kinds of things?

Looks like an ear to me:P

Or a crescent moon? 28 as in 28 mansions of the moon?

Or a not very good bow and arrow?
(the arc 11 - 28 a bow, the line 1-5 an arrow, 6-10 ??? )

To me, it looks like the spine and pelvis of XIII, and its numbering pattern suggests a middle world (1-2-3-4-5), netherworld (6-7-8-9-10-11-12-13-14-15) and upperworld (17-18-19-20-21-22-23) scheme - or any such threefold division - with 16 as the meeting point or nexus of each. It's an interesting layout.
