Seems like we could all use a "snag proof" something, and I really like the form of the boot on this old copper print block. And the patina too. I found a late 1800s printed advertisement of this specific boot online, showing it was made by the Lambertville Rubber Co. Lambertville N.J. Quite a satisfying little object.
4 1/8" x 2 7/8" x 1". Good condition, with some greening to the copper, which I like.
