The image shows a white, tulip-shaped vase, which is likely a piece of Haeger pottery. Haeger Potteries was an American ceramics manufacturer founded in 1871, known for producing a wide range of art pottery, including vases, figurines, and other decorative items. The style of the vase in the image appears to be in line with the Art Deco or Mid-Century Modern designs that Haeger produced, particularly during the mid-20th century. These pieces are often characterized by their clean lines, stylized forms, and use of matte glazes, as seen in the image. 
Similar Haeger vases, often described as "tulip" or "petal" vases, are available for sale online, suggesting that this style was a popular design for the company. The vase's creamy white color and smooth, matte finish are also typical of Haeger's production during this period. The base of the vase has a ribbed design, which is another common feature found in Haeger pottery.Given the design and color, it is likely that this vase dates back to the mid-20th century, potentially the 1960s or 1970s, a period when Haeger produced many similar pieces.
