Hello! In the early 1950s, my parents purchased in the metropolitan NY area (Koos Brothers/ Teppers) a dining set that consisted of one 60" blonde (maple/birch/bleached mahogany?) round slatted table with black enameled legs, 6 armless dining chairs and 1 open sideboard also with the same slatted wood and black enameled legs. The side board looks more like a shelving system but the lower shelf utilizes a plate groove so that dishes could sit vertically. Years ago, when I asked my mother about the provenance, she thought the set may have been made by Cosco. However, the closest thing I have been able to find that resembled this set was an ad for the Johnson Furniture Company in the front of a past issue of Modernism Magazine. Does anyone know what possible line/designer of furniture manufactured by Cosco or Johnson Furniture that may resemble what I have described? I apologize for no pictures yet. Thank you!
