unused stamps Any one out there know something about these items???

What do you have? e-mail me and maybe I can point you in the right direction.

Are you a collector of these covers ??? Iam not sure how many I have, but one is dated 1928 and I think it is a First air flight cover from(or out of) Miles City and two pilots have signed on it and so has the postmaster. I have many questions about First Air Flight Covers and stamps from the same time. I will make a list and e-mail you.
Thanks
