All five books in the Hitchhiker’s Trilogy: The Hitchhiker’s Guide to the Galaxy; The Restaurant at the End of the Universe; Life, the Universe and Everything; So long, and Thanks for All the Fish; Mostly Harmless. After researching how the publisher distinguishes first editions, I believe all five books are first editions. (Some are clearly stated first editions; for others, it’s not always as obvious). Please see photos of the copyright pages. One book has previous owner name on ffep; the other four books have no writing. I’m happy to provide more information or photos.#scifi#fantasy#humor#collectible#hardcover#fiction#galaxy#universe#gift (Shelf 3F)
