Bluebill

I found this extremely cool decoy in the mid-1970s submerged in a marsh near Clearwater, NE. Unfortunately it was waterlogged and when I picked it up by the head, it broke off. I've reattached it, and it is clearly original paint. Hollow construction appears to be very thin paper or wood stretched over a light wire frame. Anyone with information on this style of decoy I'd also be interested in.
