Rookwood Pottery vase with geometric art deco squeeze-bag slip decoration by mid century artist Wilhelmine Rehm. The design is in dark brown slip and dark blue glaze on a matte blue green ground. It measures 9 1/2 inches tall and 7 3/8 inches in diameter at the widest. Marked with the RP die-stamp, XXX for 1930, shape # 2640E and a con-joined WR for the artist. It is in great condition with no chips, cracks, firing flaws, or repairs, just a small grinding flake at the foot.
