Felix's Letter 3: Little Rabbit's Earth Exploration Inside the envelope is a letter, and it's a very exciting picture book. I have carefully stored it at home for about 30 years, but there is aging (yellowing, stains, etc.). There are no writings or markings inside. Regarding the included items, I believe they are all present, but I don't know the original set, so please check the photos. Please understand that this is a used book before purchasing.
