Extra:
Some old Dutch houses have an ornament which is a stone man’s head with a wide opened mouth. They used to indicate that a pharmacy resided in the building. Such a stone head is called a Gaper ("Yawner") in Dutch, obviously because of the wide opened mouth…(which is actually open for taking in medicine…)
