This pair of 1950s side lamps was designed by Apolinary Galecki and is thought to have been manufactured in Warsaw, Poland. They are made of curved aluminum stems attached to bakelite bulb housings. The shades are made of textured plastic which curves around the bulb casings. The bases are made of lime green acrylic glass. This creates a light effect when the lights are switched on. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
