Six (6) demitasse cup saucers (no cups) were up for sale on ebay in May 2009. They were described as being in excellent condition, measuring 4 3/4" in diameter, and from the William Foor Hotel in Washington, PA. The back (photo too small to show) said "Albert Pick & Company. Chicago. M. China. L." (same thing as the 9" flat soup bowl which DOES have a photo of the back).
