The Edwin M. Knowles China Company was a prominent American pottery manufacturer known for its high-quality dinnerware and decorative plates. Founded in the late 19th century, the company became particularly renowned in the latter half of the 20th century for its collectible plate series, often featuring artwork by popular artists. These plates were typically produced in limited editions, making them sought after by collectors.

This particular plate, "The Cocker Spaniel" from the "Shirt Tales" series, is the sixth issue in the "Field Puppies" collection. It features artwork by Lynn Kaatz, a wildlife painter, and was produced under the sponsorship of The United Kennel Club. The edition was limited to a maximum of 150 firing days, a common practice to ensure the exclusivity and collectibility of such plates.
