Wooden birdhouse, 11 3/4" high and 5 1/2" across at the base. It is made to look like a lighthouse. It seems to be a decorative piece, not really intended for use by your favorite birds.
This is from a collection of several dozen vintage birdhouses, and the former owner's family believe he received this one in about 1990. It is in good vintage condition, with some minor wear. All sides of the birdhouse are shown. There are no maker's marks. It is a solid and heavy piece.
