Well, this small teapot is a puzzler. It is brown glazed earthenware with a white glazed interior. The mark on the base is an impressed lion with one foot on a globe. The few impressed words I can make out are "TERTRE" and DEPOSE.
There was a potter in Tertre, Belgium around 1890-1900 whose name was Louis Escoyez. He exhibited at the 1893 Columbia Exhibition. But the only examples of his work which I can find are tiles. I cannot find the impressed lion mark in any of my marks reference books or on the internet.
The teapot is about 4-1/2" high. It's in very good condition with the only flaws being glaze wear to the tip of the finial, and a hairline crack on outside the lid (which does not go through to the inside). There are NO chips to the edge of the pot, just the white glaze spilling over onto the brown glaze.
