I've looked and looked, but have not been able to find another brush quite like this one, marked "Bicycle Brush" on its long wooden handle. I'm guessing the mark is a literal descriptor, and that this brush was for cleaning the spokes of an old bike? I really love its form, and especially the wire stitching, visible on its spine, which holds the bristles in place. I'd add it to a beautiful brush collection, but with its narrow head and long handle think it would also prove useful for all sorts of tasks.
11" long x 1 1/4" wide x 1/4" deep. Very good condition, with what looks like just a few bristles missing near the very center.
