One World Under Doom by John Tyler Christopher negative space variant cover, signed with a Certificate of Authenticity. Hard to find a signed copy of this book, and yes that tiny little Silver writing on the hip of Doom is the signature. John Tyler Christopher is notorious for very small signatures so you have to look closely to see it, but it is there!
See photos for condition. I do my best to make sure you will receive the book in the condition you see it in in the photo. I ship in the same way that I like to receive my books. Book will ship bagged and boarded with care in a Gemini box.
