Tiffany Studios Cobweb Table Lamp. Also known today in the Tiffany market parlance as a 'Spiderweb', this model was introduced around 1900, at the latest in 1901. Designed for combustion fuels, the first examples contained canisters within their baluster bases. To disguise the heavy visual effect that this entailed, a floral pattern rendered in mosaic tiles was added. When the design was modified some years later for electrification, as in this example, the wick and glass chimney were replaced by a 3-light cluster unit. Priced in 1906 at $500, from its inception the Cobweb was an extremely costly work of art that, ipso facto. targeted the firm's wealthiest patrician clients. It has remained amongst the most aesthetically desirable (and costly) models in Tiffany's lamp repertoire, both for the successful integration of it's shade and base, and for the virtuoso level of its handcraftsmanship. Of the seven known examples of this model this lamp is universally acknowledged to be the best in coloration, glass selection and condition. Shade: unsigned.
