Vintage Round Copper Ring Mold with hanger - Jello or Molded Salads - 1960s

Every 1960s kitchen had one or more of these! This one was my mom's -- and it is not the old, 1930 heavy copper-style mold, it's lightweight and (I suspect) more decorative than functional, although there have been one or two jello molds made in this ring! 8-1/2 inches wide at bottom (the "bottom" meaning the open side) 7 inches at the crown, 2-1/2 inches deep. Holds just a little over 3.5 cups. Remains in very good condition.
