The document in question was found by my step-dad when he travelled to Europe. He found it on one of the construction sites he worked on and took it back home with him.
What's the most info you could say about it?
It's an authorisation of a one year military leave, and the text is very straightforward and matter of fact. I'll give you a translation, in case it helps:
Ministry of War

I have the honour of praying you to deliver a new leave until 1st April 1867 to the recruit Lempereur, [François?] of the 1862 levy, primary education teacher, incorporated to the regiment of which you are quartermaster.
