Vintage art pottery vase, Full moon winter themed elegant artist signed pottery

A gorgeous hand made pottery vase, signed by the artist. In a deep blue on black, with white speckles reminiscent of the night sky, a full moon hangs low just outlining the berry bushes in winter time. The glazing finish looks like a combination of airbrushing and painting techniques on top of a wheel thrown vessel. Overall this item is in good condition without any chips, cracks or repairs. There is crackling to the glaze, especially on the inside of the pot. I did test it by leaving water halfway up the vase for a week and it was not leaking, weeping or otherwise coming through. I have sadly not been able to make out the signature on the bottom. Dates ca 1970-1980s Size: 8.5 inches (21.5 cm) tall, ca 7 inches (18 cm) diameter at the widest point
