@Crazy Horse Lady,
just for grins, see if you cant find an appraiser who specializes in Bertoia's work and ask for some advice with the picture(Ssince its so close to Bertoia's brutalist style, maybe its a knockoff, an original, or one done "in the style of"... Harry Bertoia.
Hint: if it is a Bertaia, it could be worth in the tens of thousnds or more. (some of his radiating armatures are worth over 100K.
So, its in your court. Good Luck
