Circa 1951-1959: The 36s bowl was the last piece designed for the Harlequin line by the original designer of Fiestaware, Frederick Rhead. Rhead was an Englishman who used many ceramic terms inherited from the famous Staffordshire potteries that he would have been familiar with. 36s, for example, is a reference to the number of pieces that would be sold in a bundle. 12s would have been a dozen, so 36s would have meant that 3 dozen could easily be bundled, shipped and sold together. This example in the harder to find 1950s color of gray is in excellent condition, without damage or signs of use. The bowl measures 5 1/8" wide x 2 1/2" tall.
