This is a very rare C. Jeré (or Curtis Jeré, often seen without the accent) brass plated skyscraper lamp. The lamp has two sockets in the base casting light upwards giving the evict of many windows leading up the column.
Curtis Jeré is a compound nom de plume of founding artists Curtis Freiler and Jerry Fels, who combined parts of their own names to create the C. Jeré signature.
This lamp is in excellent condition for it's age with only slight signs of wear
