Waaay outta my reach, but sweet Elsies- The framed picture behind one of the gun photos- two grouse- Robert Abbett perhaps?
I first saw his work in the 1977 Fall issue of the old Gray's Sporting Journal-- with a poem by a Don Titus- entitled "The Grouse Hunter"--
I don't think that is Abbett, Francis. This is his style, it hangs in our home.
Shooting the High Field-- You are most likely right- Not a Chet Reneson(I have an artist's proof of his "Neighbor's Field" winter goose hunting scene, not a Peter Corbin-- Perhaps an Alden L. Ripley or a Odgen M. Pleisser- Whomever the artist may be, very nice indeed. Almost makes me want to be a NE grouser, instead of a Midwest waterfowler- almost!!!

Very, very nice Crown Grades, billgrill. Thanks for posting them
