Vintage envelope, MASSEY-FERGUSON INC. Kansas City Kansas, picturing the MF tractor logo, in n-mint unused new old stock condition. Nice clean envelope with the flap stuck shut. Size is 4 1/8" x 9 1/2". Scans show the front, back is blank. The black border is so all the edges can be seen and is not part of the envelope itself. NOTE: All of the envelopes I have listed are guaranteed to be 100% authentic originals. They are all clean, unused and new old stock unless otherwise noted. Thank you for your purchase I appreciate it.
