Somewhere on the Net (in America, naturally) you can buy this charmer, called “Purcival Pig” (!).
The maker doesn’t take anything for granted. The good luck is ensured with not one, not two, but with four (yes, 4) symbols:
A pig (where in the world is a pig a good luck symbol?), a horseshoe, Lydia Ladybug (I don’t know who or what that is either) and (of course) a 4-leaf clover (firmly attached to the pigs fat behind).
