HISTORY OF BUENILUM:
The Buehner-Wanner company produced Buenilum pieces throughout the 1930s, '40s, '50s and '60s, making mid-century modern decorative, kitchenware and food service items such as serving trays, lazy Susans, relish dishes, bowls, pots and pans. The company was sold to the Pfaltzgraff company in 1969, which continued to make Buenilum pieces until closing the line in 1979.
Vintage hammered Buenilum pieces with the initials BW flanking an image of a castle turret on the back, along with an imprint of the name Buenilum, are considered valuable antiques as of 2014. They are known for their workmanship and design; some are even found in museums.
