My Black Piggy Bank

I've had this piggy bank for many years. I don't remember how I even came to have it. I've tried to find info on it but haven't been so lucky. I've looked and I've not been able to find any signature or markings of any sort. I love it because it's one of those piggy banks where you would really have to "break the bank" to get your money out. It looks to be hand painted which is awsome! Besides all this, how many black piggy banks do see? I love that it is so different.
