By William Harnden Foster, and possibly depicting his son with Foster Sr's 27" barrel 20 gauge DHE SN 225905.
And BTW: the Ithaca NID Skeet Special was advertised in the July 1926 National Sportsman, only
2 months after the game was named! Was the Ithaca Gun Co. tipped off in advance of the announcement in order to accelerate production of a designated skeet gun?
And why did the skeet logo appear two years later on the L.C. Smith “Skeet Upland Special” and not on that gun?
