Well unfortunately I was using this evelope to store some stamps to soak about 20 years ago and then came across it last night and realized it was of interest.
Thanks to this forum, I am noticing covers and cancels and items I never even looked at before.
Well my grandfather used it for his "Don't Know" stamps back in the 30's and I used it for the "Seychelles", but I thought the military training camps cancel was interesting.
Addressed to The Fenton Company apparently an "export merchant" according to my Google search.
