Antique 1910 advertising calendar plate by Harker Pottery Co. of East Liverpool, Ohio, marked "Semi-Porcelain" with the company's bow and arrow backstamp. Approximately 7 in across. The front features a lovely Art Nouveau-style floral bouquet in soft pink, yellow, white, and coral tones surrounding a complete 12-month 1910 calendar framed by delicate green vine scrollwork, with "Compliments of W.M. Smith, Buxton, Kansas" stamped below — a small-town merchant giveaway plate from the golden age of calendar plate advertising (1905–1915). Crazing is present throughout the glaze, which is typical and expected for plates of this type and era. There is also visible wear and loss to the gold rim trim. No chips or cracks. A charming piece of early 1900s Americana advertising history, especially appealing to Kansas-area collectors or calendar plate enthusiasts.
