I had to share this link from viralnova.com on what you may find on the edges of your old books. This is kind of driving me nuts right now because I know I had books where each edge of the page was printed just a teeny-tiny bit around the edge of each page. I have a sneaking suspicion this is what I had in my hands.
Now I am debating if I want to go in my basement and start digging through boxes and bookshelves full of my books.
Maybe tomorrow.
Have you ever seen this?
