German soldiers ration book page ?

[jwp]

Here is an interesting find from my local oxfam shop today, I think it must be a page (unused) from a german soldiers ration book, not mega exciting as finds go, but for me a little piece of history to hold in my hand !.
On the rear of the page seems to be the address of a young lady in Holland, wonder is this is someone the german soldier met or maybe an allied soldier who just used it as scrap paper !, either way to me an interesting find for little money,
all the best,
John.
