This is another product of the joint venture between Marvel Comics and Thomas Nelson Publishing (A Christian content specific company). It's the first of a series of Christian Classics. The idea was to take the old Classics Illustrated approach and produce comic book versions of famous Christian works. This is an adaptation of John Bunyan's famous 1676 work. The producers updated the story so that it takes place in the 20th century, but it is an otherwise faithful rendition of the Bunyan work.
