Here's a nice cacheted cover for the U.S. Navy ship USS Richard L. Page. As far as I know, it doesn't commemorate any specific event, although it was obviously cancelled on Veterans Day.
Postmarked: HC - USS RICHARD L. PAGE (DEG-5) - November 11, 1967
Cachet: Black rubber-stamped shield design featuring a knight's helmet, cannon, missle, and an open book.
Condition: Clean and neatly label addressed, with a mild crease just to the left of the cachet.
MULTIPLE ITEM SHIPPING DISCOUNT: I will ship up to 4 covers for the single base shipping charge shown. For purchases of more than 4 covers, the shipping charge will increase by just a small increment for every 4 additional covers.
