These owl planter vases were made by Napco in the 1960s. They're about 6 inches high to the tops of their ears by about 7-1/2" long overall. The glaze is somewhat glossy, causing white spots in the photos that are not present on the planters. There is a little white paint transfer to the back of one owl, on the lower left side of the rock. That owl also has a small paint scratch to the back of the head, right along the rim opening edge. The other owl has a small flaked chip under his tail, virtually invisible unless viewed from below (see the closeup, picture number 3).
The bottoms are marked C-6565 Great Horned Owl. Each also has a price sticker reading Char-Ral Floral, Jackson Wyo. The original Napco Japan stickers are not present - these owls are also sometimes found with Napcoware stickers. They've been together for the past 50-some years so I'm selling them together, but I can sell them individually if you only want one.
