Here is another bottle I have. Don't know much about bottles. It is 7 inches in height. It is a very light blue green in color. On the front of the bottle it says Porter's. On the left side it says cure of pain. On the right side it says Cleveland.O. It has no other markings. It has seems that run up the sides almost to the lip of the bottle. If anyone could date it or tell me more would be great. Take care Jeremy.
