Each of these Knowles Columbia Bread and Butter plates is decorated with a pastel multicolor design of several types of summer flowers, dominated by a beguiling deep pink rose on vivid green leaves. The design rims each plate with three flower arrangements in descending sizes. The scalloped edge is trimmed in gold.
Made by Edwin Knowles from the 1940's until 1963, these plates are unmarked. I have matching pieces listed with two different backstamps; the black underglaze Edwin Knowles Urn mark that was discontinued in 1948, and the gold signature "'K' Knowles" backstamp that was introduced in 1953. The Knowles plant ceased operation in 1963.
Each Semi-Vitreous China plate measures 6 inches in diameter. Offered as a set of six, they are heavily crazed, but there are no chips.
