Another example of a thing made for one purpose, but which, recontextualized, feels quite like an artwork, this one feeling very Duchampian to me, including for his ongoing interest in thresholds and portals (doors, windows, peepholes, glass, etc..) I believe it was made as a salesman sample for sliding screens, here with three screens, each with handles for sliding them in one direction or the other. They can all be slid, one by one, to one side or the other, making for an opening on one side (a portal) and three layers of screen on the other--which makes it also something of a moire pattern making machine!  For me there's a great stage set quality to it, evincing a drama yet to unfold--like an architecture for a confessional, or for a game of telephone. Anyway, a terrific and evocative object I think, sort of a minimalist distillation of a permeable divide. 

The screens can be configured in any positions, left, right and in between, plus one of them can be popped out (as shown in photos.) Solid and sound condition, with general wear/rust to the black metal frames around the screens. All slide easily.
