There is a reading room in the student center at my college which, due to its one circular glass wall, is known as the Fishbowl. It is mainly used as a very quiet study room, but it does have a sizeable collection of reading material, all schmancy dollhouse-looking leather-and-gilt editions of classic books.
Anyways, I recently borrowed a volume of several of the French fairy tales for tea time/bedtime reading...and I found a love letter in the end papers!
The really magical thing? This is the second letter I've found from this couple's correspondence. Last semester I borrowed another book of fairy tales from the Fishbowl, illustrated by Dulac, same as this one, and found a letter in it from the same girl to the same boy. I'm thinking they were using their mutual favorite books as a sort of secret mail system. Have you ever run across a piece of a correspondence before? I hadn't until these.
