OK… I'm new to this site, and I'm glad to be able to seek expert advice …
I'm thinking of breaking a golden rule but perhaps for good reason. I have an old album with covers mounted, but the collector cut the bottom half of the covers off. This particular cover I believe is some kind of soldiers mail from World War I. I have not yet identified which Washington/Franklin this is , but I believe the left stamp is a "jumbo"...... should I soak it? Isn't the cover pretty much worthless because the bottom half is removed ?
