Arguably the single most heavily aged card in our entire stock, it looks like every day since 1915 has been a battle for it.  It has a message that we can’t decipher on the reverse, but was not postally used.  The card came to us in a clear sleeve, and honestly we haven’t had the nerve to open it and see if all 12 pages of that little calendar are still there.  They should be — but no guarantees.  Aged, busy, and Grade: 3
