This piece measures 5 1/2" x 4 1/2" x 2 1/2" tall & weighs right at a pound. Hand hammered copper with hand poured bronze or brass. I picked this up at a shop in northwest Alabama. I've never seen a piece like this except one time in a museum. No clue who made it, but they had great abstract skill.  There is some natural patina forming as seen.   Please see photos for details of the exact item you're buying. As always, if you have any questions just ask!
