2 covers mailed to Best & Co. Grand Central Station dated May 14, 1959 & the other I cannot make out the exact year in the 1950's - July 30, 195_. One is mailed via the Air Force Postal Service.  I covered the names of the senders as a privacy courtesy gesture.  Covers are cut out on the lower edge when it was opened for the Air Force cover, and the other was cut on the lower and the left edge.
