I'm needing a little guidance on two stamps I
inherited from my great great aunt. She was a banker married to the mayor of a small town in Texas. I'm having a hard time determining if these two stamps are really the Scott Catalog Stamp 181 and 179. The paper on the back of the 181 is white with what appears to be no gum verse the 179 which has apparent gum. Can anyone help with these two stamps please
