The Alvin covers on the 1995 fullscreen tapes are my favourite, and are what my DVD covers done by Metallaxis are based on.
I think the 1991 widescreen edition was the first time a movie had a VHS release in the letterboxed widescreen format. If I remember, the Star Wars Trilogy was released along with Alien and Die Hard under the slogan "Widescreen - as they were meant to be seen". Is that trailer included on your tape? I have it on Die Hard.
Is C3PO's tractor beam line included in this 1991 edition?
