This appears to be a piece of art pottery, likely a small ewer or pitcher. The style suggests influences from the Art Pottery movement, which emphasized handcrafted, decorative ceramics. These pieces often featured unique glazes and organic forms.
Art pottery gained popularity in the late 19th and early 20th centuries, with studios emerging across Europe and America. The two-tone glaze, with a brown drip glaze over a light blue base, is a common characteristic of this style. The handle and spout are integrated into the design, reflecting the emphasis on form and function.
