Unmarked (Japan, I think) vintage wall climber figurine, a cute little monkey!
This has a closed loop made by the arms, so it works well on a peg or an upright rod like a garden stake or a large plant. I've never seen a climbing monkey before, it's usually cats or squirrels.
He's about 6 1/2" long end to end. Condition is very good, gently used, no chips, cracks or repairs.
