Well, the first mask I had.. It was the H2 version. Made to look more round like it did in that film. Dick Warlock played Myers in that one and the mask was fastened around his head with velcro in the back and was severely rotting and worn. The hair had gone damn near blonde, back to the Kirk color. Also the white paint had started to come off in places and the skin color underneath was showing through a bit. So the look was still nearly the same, but a bit more round and filled out.
The new mask is made to look like the original one, white faced, brownish black hair and a lot less worn. Not to mention it looks like the mask worn by Nick Castle in the film, hanging down and showing a lot of the detail in the cheeks. Only Myers freaks like myself really notice the subtle differences....
To me they were the best looks in the films, the rest just looked off and not Kirk-ish enough for me. Though I have to say I really like the new design of the remake. It's close enough for my taste and leagues ahead of what has been done for the last 6 films.
Here's the H2 mask again... on the right.
