I think I have two somewhere. They were indeed AEG, I think art was one from L5R and one from Warlord. They were mostly used for carrying promo cards for tournaments from organizers. Due to that they're probably hard to find.
I have 19 of them, but I wish I had more! They are so much better than everything else. After a hiatus of 15 years I started playing again, now that my boys are old enough (11 and 14).
