Robert Silverberg Vintage Paperback books set of 2

Robert Silverberg Vintage Paperback books set of 2. “Next Stop the Stars” and “The Silent Invaders”. Both are in okay used condition with some bends on the covers and yellowed pages from age. Condition is subjective. I recommend that you zoom in on all photos to make your own assessment. I research on the internet, dealers, books, etc. I do my best to describe each item, but I am not an expert. You are encouraged to do your own research. Unintentionally I may miss something. Descriptions are based on what I see and any information I collect. In most cases I am not the original owner. Item is in the same condition as I purchased it. I do clean the item but I do not do any major cleaning of the item. I leave that up to you. Although I live in a non smoking home, I do not guarantee that the item(s) originally came from a non-smoking home or from a home which does not have pets. I don’t sell items that have bad odors. Please ask me questions before you purchase. Most of all, I want you to be happy with your purchase.
