every vhs is sold in clamshell so this has to i have never seen that copy before but believe since gmd came out in as disney's th animated feature in july whereas alice in wonderland came out may 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 version
