This early plate is from the Southern Pacific Railroad. It dates from between about 1900 - 1912. The pattern is Harriman Blue. A very flexible size at approximately 7 inches across, this could have been used for lunch, a salad, cake or toast.
There are two markings on the underside: the Southern Pacific round Sunset Ogden & Shasta Route logo and an impressed MADDOCK'S AMERICAN CHINA. Our restaurant china book by Conroy confirms that this Maddock mark was used in the earliest 1900s.
Condition is excellent and a fine display. The scrolling blue rim swirls are old fashioned and attractive in varying shades. There are light surface marks from use but you must tilt it in bright light to see them. There are absolutely NO cracks, chips, flakes or repairs.
IMPORTANT: The dark line on the underside is a manufacturing flaw. It is a shallow fissure in the pottery that has become stained over the years. It is not a crack. Also, and impossible to notice unless you tilt the plate in ligh, there are several tiny glaze imperfections on the top surface.
This would be a nice addition to a collection of early Southern Pacific dining car items or a grouping of Harriman Blue dinnerware, as the pattern was used by several different railway operations.
