Here is the cover art for the 20 October Blu-ray/DVD release in the US from Kino Lorber of The Oblong Box. Interestingly, according to The Vincent Price Exhibit curator Rick Squires, it wasn't the first time that American International Pictures had used the same illustration. As you can see below, it was used as pre-publicity for the US release of Witchfinder General (The Conqueror Worm).
Kino's Oblong Box release will include an audio commentary from film historian Steve Haberman and one very exciting extra that I have never seen before, the 10-minute 1969 World Wide Adventures short Annabel Lee narrated by Vincent Price. Transferred from an original 35mm print, this has come from the personal collection of Price fan and Drive In Super Monster-Rama head honcho, George Reis. Now this is something worth checking out.
