These weren't tied by Dan Bailey, they're flies that came out of the fly bins at the Dan Bailey store in Livingston sometime in the early 1960s. The Pink Wulff is a fly you don't see in the stores much anymore. It used to be a popular fly. The other is the Bi-Fly, so named because you could fish it wet or dry. The only place I still see the Bi-Fly (or flies like it) is during Salmon Fly season on the Big Hole.
