That is a wonderful peace of iron. I have never seen any piece marked Galveston, TX before. Prior to the 1900 hurricane that wiped out the island, it was known as the wall street of the south. There was a lot of industry and business there. After the hurricane, it did not recover and Houston went on the become the major port of entry. Thank you very much for posting these photos. That is a great piece of history. I wish I knew something about it.
