On the official website for the box set, Harry Potter Wizard’s Collection unveiled labels that hold sketches by longtime Potter set designer, Stuart Craig.

Craig is one of the more important behind-the-scenes crew members. He led the design team on all of the sets you’ve seen in every Harry Potter film. He also played a huge role in designing the theme park(s).

Wizard’s Collection includes two sketches, it appears. You can see them below (of Hagrid’s Hut and what seems to be the Little Hangleton graveyard from Goblet of Fire):

The complete box set includes each of the eight Harry Potter films and a few new special features. See a complete breakdown.

Wizard’s Collection will be released September 7.
