Vintage art pottery matte glaze vase. Displays nice, but has a couple of tiny flaws. It has a pinhead speck on top rim; a couple of black lines, (these are not hairlines); and a teensy fleabite near bottom rim, (old flaw). Incised mark on bottom: 5 A or S A). This vase has faint blended colors of blue and light blue. It is 4 inches tall. As stated, it displays very nicely. Not sure who made it; it is well made and hefty for its size. 9/13
