"Rare Bird" Signed NJ 1 Gallon Crock

Year: 19th century
Weight: 5.8 lbs

one gallon pot made and signed by J.Zipf , Union Pottery, Newark New Jersey. I have never seen a bird on any pieces attributed to this potter so I'm calling it rare. There are a couple tight hairlines and one or two small chips but still a desirable design and size from a well know later 19th century NJ potter, you probably won`t find another.
