Vintage figural jewelry comes in many styles, but generally is available in brooches, pins, pendants, and charms. As an example, a person who loves cats might want to sport some figural cat jewelry. It's a fun way to express what your love is for a particular animal, gardening hobby, bird watching etc.
Recently I acquired a lot of vintage pendants, and charms, which included some figural jewelry, and I put the vintage cat jewelry together. These pieces will probably go into my eBay listings soon.
The pendant that says, "Here kitty kitty." is inside a bubble like shaped pendant. I suppose if you like these vintage figural pendants, that it must mean you're one cool cat!
