Circa 1960's, no maker's marks but most likely California. Appear to be made of a mixture of pottery, cement and fibre glass, and have a textured surface. These are quite large, each measuring 15.75" tall and 20" diameter at top rim tapering down to the base, and weigh approximately 45 lbs each.
Condition is good vintage- these planters have been used. Each has some scuffs and a few shallow chips mostly around the bottom rims and some traces of dirt on the interior.
Price: $695/pair
