retro 70's vintage, old owl cement planter for camp or cabin

We love those 70's owls! And here's a piece we've never seen before, a very large and very heavy planter, a great companion piece to those 'big owls in branches' lamps.

This measures 10 1/2" tall, and will fit a flower pot about 9" in diameter. We think this is a cement type material, rather than chalkware - though it might be plaster in cement? It's solid, and really heavy.
