The painting in the background is not really abstract but the wiry pieces in front are. The closest thing in my head that I can reference to them is hangers- but that doesn't match up to the shadow shot. Your abstract game has not been easy!!
I looks possibly like the tops of several plate stands (without plates) or small easels for displaying little artworks — like photos — or book stands??
Great abstract. As you seem to be doing the Abstract August challenge do you want to have a Get Pushed Challenge that ties in with it? What do you think of street art as a Get Pushed Challenge - it could be graffiti / murals or structures (like clocks, sculptures etc)?
