Well, the first dozen, or so on my list are impossible to add pictures of, as, as far as I know...there aren't any! That brings me to this one:
(Picture by Argyle Acres)
Zuni (Ayers 1931)
very, very similar to "Indian Chief", another Ayers introduction.
But, I really suppose you're thinking of more "modern" irises, so, Zuni Echo (Blyth 1986), a BB, is up pretty far on my list. it "sounds" very nice (haven't seen a picture of that one ,either !).
But that one's getting a little "long in the tooth", also, I guess! So , sticking with the "Zuni" theme, there's an SDB from 2012, Zuni Thundercloud, that's up towards the top of the list, as well.
