This is the Fantasy Trip Companion - both part of the game, and a book about the game. It's very limited print run.
The TFT Companion is a collection of articles, starting with Steve Jackson's original designer's notes and errata published in The Space Gamer in 1980. It includes a collection of optional rules, expansions, and adventures created by fans for the magazines of the day, and closes with a collection of articles posted online in 2018.
