A really basic design, a blu-ray and book combo where the book closely resembles the one being read by Peter Falk in the movie. I approximated the book cover and made it look brand new instead of old and worn.
In the front flap a disc for the movie is stored. I suppose another disc could be held in the back flap if warranted for Special Features.
UPDATE (Sept 1st 2018): Criterion recently announced their 4K release for the Princess Bride that will be in a book cover. It’s gorgeous, as all Criterion stuff is, but I would’ve liked if they went for a screen-accurate version.
