"Hammer and Rock"

This painting is done in acrylic paint on a primed piece of hardboard and is 5"x7" in size.  The hammer head is the oldest part, I suspect made in the 1800's or early 1900's.  It is obviously a crude design, yet here it is in the 21st Century.  The handle probably has been changed several times, as this one is about thirty years old; just a guess, but it looks mass-produced.
