This is the vintage Kaiser Porcelain Collector's Plate "The Frog King" from the Classic Fairy Tales collection, designed by artist Gerda Neubacher and made in West Germany. It features a gold-trimmed porcelain border and a painted scene of a crowned princess in a purple dress next to a stone fountain with a crowned frog and a golden ball.

This image reveals the authentic Kaiser W. Germany hallmark backstamp for your collector's plate. The German text confirms it is titled "Der Froschkönig" (The Frog King), which is the first plate in a limited-edition series of six classic fairy tales painted by the artist Gerda Neubacher. 

The backstamp provides a few key identifying specifications for this specific piece:

• Limited Firing Window: The production run for this series was strictly limited to a brief 50-day firing period. 

• Unique Identification: Your specific plate is hand-numbered as G-1475.

• Bradex Registry Number: It is officially cataloged under Bradex No. 22-K.4-5.1, a system used by the Bradford Exchange to track collectible art plates. 

• Wall-Hanging Design: The two small holes molded directly into the top of the white base ring are intentionally built-in to let you run a wire, ribbon, or heavy string through for easy wall display
