Vintage Frost's Hair Wing Flies  #8 Ring Sproat Hook package of 3 retail card made by the G.W. Frost Tackle Company aka Frost Brothers Tackle Company. The 3 flies look like they've never been used: ...Grizzly King Fly...Royal Coachman Fly...Yellow May Fly.  Since it's hard to see in the photos I want to point out that cellophane envelope has multiple large tears and is poor condition. See photo's for additional details.
