I ran into another bit of info yesterday,, A William P. Bohn was mentioned in the papers of a Clarence Joseph Bulliet (1888-1959) !! They are in the archives at the Smithsonian, box 7 folder 8 of the Bulliet papers!! Evidently this Bulliet was big into the arts !! Might have the info online but I didn`t go through it all !!
I couldn`t see what the sculpture was,,looked like an old fashion artist easel to me !! You are talking about the tripod item aren`t you ??
