When a book is in development, a sample is made so the designers can get a feel for the book. Some have writing and some are printed covers with the inside blank.
And there was a giveaway (now closed) at the Craftside blog and I won one of them. How cool is that. I can't wait to see what mine is like. What a nifty journal it will make!
