I bought this 466 page book in 1990 at a B. Dalton Bookseller store in Lacrosse WI (receipt included) and have kept it in good condition. It does show some wear because it was my go-to book for years.

The product is "The Twilight Zone Companion" by Marc Scott Zicree, a 30th Anniversary Edition published in 1989 by Bantam Books. It is a trade paperback book written in English, focusing on the topic of TV & Movie, specifically related to "The Twilight Zone" series.
