Antique sepia "pure fresh cream from the wigtownshire creamery Ballymoney co Antrim" jar

I found this while digging in my auntie garden I can't find much information about the Ballymoney branch of wigtownshire creamery but as this is the brown (sepia) ink it is pre 1912.If anyone can help me with information about it and how much it is worth It will really help me. Except the chip on the front it is in pristine condition.
