This little ceramic Eiffel Tower made for the tourist market if about 4” tall and 2 1/4” at the base. Open the hinged upper section to reveal a space in the base, the opening about 3/4” square-ish and 3/8” deep. A bit of wear to each corner of the base. The upper space is about 3/4” and decreases in space as you near the spire. I’m not sure what the metal is. Common but rather cool.
