In recent correspondence from the Archives Dept. of Syracuse China Company (copy available), I have conformed this plate was made in 1977 as a sample plate exclusively for the Homestead. As they say "Your plate is a sample plate, #23923 is the sample number. The Homestead ordered this item one time. Our records do not show how many plates were produced for that order." In any case I doubt that many collectors have seen this beautiful plate, is a chance to add something unusual to your collections.
Much like the collectible Nature Studies series produced by Syracuse China, this plate has a beautiful red and blue floral design of Irises on its front. This plate is a service plate, 10 3/4 inches in diameter, used only by the hotel for presentation purposes in their dining room. To quote again, "The Elton Service Plate, with its wide rim, thinner cross-section, and no roll under the edge, was intended for tabletop presentation..... The decoration was used on the service plate only, and not on the larger set." Given this purpose and that its clearly a sample, the plate is in mint condition and very uncommon (perhaps unique).
