The book is a collection of short stories, documentaries, and possibly some poetry and such.  I remember stories about a runaway train, a human cannonball and possibly some sort of road trip.  I think there was a board game printed in the middle of the book that related to one of the other stories.  There were black and white photographs of the human cannonball performers, and they talked about knowing lots of languages and sometimes switching languages mid sentence.  I remember it having a blue cover but that may not be very applicable.

I know it was published before 1980 and probably before 1970 or possibly even in the 60s.
