Vintage Pink Glazed Ceramic Vase or Planter with '542 USA' Mark

This item is the base of a ceramic vessel, likely a vase or planter, characterized by a smooth, glossy pink glaze on its exterior and interior base. The visible portion of the item is circular at the base, with a slightly raised outer rim that has an unglazed, off-white or light beige rough finish, indicating it's the footring. The primary color of the exposed base is a muted, pastel pink. Centrally located on the recessed base are impressed markings: '542' appears prominently above 'USA'. Both markings are clearly legible and are also glazed over in the same pink color as the base, suggesting they were applied before glazing and firing. The impression of the letters and numbers is deep and uniform, indicative of a molded or stamped manufacturing process. There are several small chips or abrasions visible along the edges of the unglazed footring, suggesting some wear and age. One more prominent chip is visible at the 6 o'clock position in the image. These indicate typical wear for a used ceramic item. The overall craftsmanship appears solid, with no visible cracks or significant damage beyond the minor chips on the footring. Based on the style of the impressed 'USA' and the pastel pink glaze, this item likely dates from the mid-22th century, possibly the 1940s-1970s, which was a popular period for glazed pottery with numeric model identifiers. The item's condition, apart from the footring wear, seems good, retaining its original glaze integrity.
