My wife and I bought 4 tubular chrome art deco-style chairs (see pictures) from the site of an abandoned office building in St. Louis around 20 years ago, and we've had them ever since.
My wife, who has a rather keen eye for such things, is convinced that they hold some degree of historical\design\architectural significance, but I've never been able to identify them. Through google searching I've found similar chairs associated with names like Kem Weber, Mies Vonder Rohe and Wolfgang Hoffmann, but I've never found the exact chair and I've been unsuccessful in determining whether our chairs are vintage "diamonds in the rough" or simply knockoffs from some place like Sears.
I've uploaded two pictures of one of the four chairs, one with the original cushions in place (not the original fabric), and one without. The original cushion covering was a pea soup green vinyl material. Although I would describe the chrome as being in good condition for its age, there are some rust spots around the legs at the back (see 3rd picture). I think this would come off with some chrome polish and elbow grease, but I couldn't swear to it. Also, one of the arms on one of the chairs does not mount securely because the threads into which the fastening screw attaches appears to be stripped. There is no problem with the other arm of this chair, or with any of the arms on the other 3 chairs.
I would be forever grateful to anyone who can identify these chairs and assign an estimated market value to them. If you are interested in buying them, we are open to offers. Thanks in advance for your reply, and thanks again for this wonderful service.
