You are looking at an old cotton banking money bag from the 1950's. It measures 17 1/2" wide and 36" long. This old bag was given to my grandfather way back then by a relative who worked at "The Birmingham Trust National Bank" in Birmingham, Alabama. FDIC is printed on the bag as is "Federal Reserve"......
It has aged well and would be a great collectible if you like this type of thing. If you have any questions, please ask me. I know nothing about banking bags but it is in fairly good shape with no tears in it. Thank you for looking!
