Green Glazed Teapot with Mushroom Lid Studio Art Pottery Unusual Style

Studio Art Pottery Green Glazed Textured Teapot with Lid Unusual Style - It has a sort of mushroom style lid. This is approximately from the 1980's.  It's from an estate sale where they did a lot of travel and collected souvenirs from around the world.  I really don't know a lot about it except that it's a very cool piece. Measurements:  8.5" tall x 3.5" base
