This is a nice large letter "O" cast from Bronze.
We are selling as found. It has some silver / grey paint that can be easily removed. This will polish up nicely and have a great bronze patina.
See the photos for details.
We are guessing that these may have come from a bank or some other type of advertising sign.
We just came across some similar sized NEW letters made of cast aluminum (not bronze) direct from the manufacturer and they were actually higher priced than this!
