Offered is this beautiful lamp with an iridescent glass shade and a metal base, that in all likelihood, was made by Loetz. Overall, the lamp is 22 1/2 inches (57 cm) tall, while the shade is 11 1/2 inches (29 cm) wide. Except for a few rim-chips that are typical of these old lamp shades (hidden while the shade is in place - the largest one shown in picture), the glass is in good condition. The green and purple iridescent colors are prominent in the shade (see pictures - like typical iridescent glass of that era, the color of the shade changes, depending on how the light hits it). Both the shade and metal base are unmarked (except for the number, '158' inside the ceramic light-socket). The original wiring was changed - so the wiring should be safe now (the original 'on-off' switch at the bulb-socket is now non-functional, a newer rotatory 'on-off' switch by Leviton is functional now). This lamp has the European ceramic bulb-socket that was typically used by Loetz in their lamps. A somewhat similar-looking Loetz lamp is shown on page 118 of Alaister Duncan's book, 'Art Noveau & Art Deco Lighting (shown in last picture here for your convenience).
