`  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.`
