This is a Mary piggy bank that I received as a novelty item from Lovers House back then. I took it out of the box and have been displaying it ever since. I have never put any money in it. The area around the money slot is a little sticky. There are no noticeable stains, but since it's from that time, it looks like it has yellowed from sun exposure? I would appreciate it if you understand. Lovers House Kenmeri
