O127 Issue Jan. 1983.
1¢ x 40 - Salinas, CA June 11, 1990
A newer 1¢ was issued July 1989.
The envelope is quite large (something you might send personnel files in) - 10"x15". No idea on contents
Rate - 1st oz was 25¢ each additional 20¢. Not sure how they came up with 40¢.
Did the military follow postal regs?
Maybe just trying to get rid of old stock?? Or not that heavy.
