1. Every VHS is sold in clamshell, so this has to. I have never seen that copy before, but believe since GMD came out in 1986 as Disney's 26th animated feature in July 1986, whereas "Alice in Wonderland" came out May 1986, so I say that there is a trailer for "The Great Mouse Detective". I also say that they're previews for "The Sword in the Stone" and "Alice in Wonderland" on there because they always have trailer for some their VHS release. If they have only one movie released in the WDC series for a year., then they could've had a trailer for that at the beginning of the movie. However, if they have more than one movie released in the WDC series for a year, then they could've had trailers for those movies at the end because it is like "Beauty and the Beast" (my number one favorite movie). Ryan and Marco have the October 1986 version.
