Very nice Bill,
This is the pattern I got out of Paul Marriner's book.
Hook: Up eye Salmon hook
Tag: Small oval silver tinsel.
Rib: Small oval silver tinsel.
Body: Pearl Uni Axxel Flash.
Wing: White bucktail, pearl blue krystal flash (#14) under light brown bucktail
Collar: Grey heron and silver pheasant as a collar.
Cheeks: Jungle cock.
Head: White with blue band.
Funny thing about some of Marks Patterns, they seem to evolve over time. The Picasse is an example of this. He started tying it with a cheek of amherst pheasant and later deleted this and used a silver pheasant collar. The attached is my version of the fly.
