This is a square salad plate with a gadroon border and gold trim, made by Harker, and decorated as a souvenir for the state of Arizona. It is not marked, but I have identified it as Harker based on the shape, border, and decoration. The plate is 8" wide. The colorful scenes in the center are of a sand painter, Coolidge Dam, rug weaver, the Grand Canyon, Sahuaro Forest, and the State Capitol. The plate is in excellent condition with no chips or cracks.
