Danish wall lamp with wooden arch and pearl shade lampshade, 1960s

Danish wall lamp from the 1960s with a wooden arch in bamboo. The pearl shade lamp was designed by Lars Schiøler and manufactured by Hoyrup. The lamp is in good vintage condition. The transparent tube on the inside that serves for the dust has a small tear (see photo) but this is not noticeable and not visible when the lamp is on. The outside has no tears or holes, only a small stain at the top (see photo).
