I actually don’t know, and I’m coming up blank on my searches. So, I’m releasing this one to my followers— does anybody know for certain whether enlistment papers were obvious when received?
So the proper name for them was an ‘order to report for induction’ and I can’t find any envelopes online my grandfather’s had the local draft board address on it in a window. Unfortunately the one website I did find with info won’t let me direct link to the image, but the bottom left has a copy of one – the stuff inside the box would have shown in the upper window. http://www.nationalww2museum.org/learn/education/for-students/ww2-history/take-a-closer-look/draft-registration-documents.html
