Sci-fi Book Covers

A set of four antique sci-fi paperback front covers, separated from their books. Two Star Trek (fave!) covers, and a Heinlein and a Clement. Wonderful vivid art and typography. Their spines are intact too. They don't have backs. 

I discovered them in an old bookshop, where they had been already separated, possibly because the paperbacks were so damaged they were unsaleable.

You will receive the exact four front covers shown here, packaged safely in a rigid envelope.
