Blues Brothers: Private is a book published in 1980, designed to help flesh out the universe in which The Blues Brothers (the first film) took place. "Private" was written and designed by John Belushi's wife, Judith Jacklin, and Tino Insana, a friend of John's from their days at The Second City. All copies of the book came with a detachable poster that was a replica of the posters used to promote the band's gig at the Palace Hotel Ballroom in the film The Blues Brothers.
