atmcashpoint, 
I took a stab at recreating some of the early Edison sprites seen in @danielalbu 's Gary Winnick interview. They're a lot shorter than the versions in the published game, and look a lot less squashed when they're seen with aspect ratio correction (image 3).
You can also see the shorter early sprite for Wendy in a piece of WIP art Ron Gilbert posted on his blog a number of years ago.

An attempt by me at recreating some of the early Maniac Mansion sprite art shown by Gary Winnick in his interview with Daniel Albu. I've posted the early art for Weird Ed, Dr. Fred, and Nurse Edna next to the final versions. It's really obvious here that the sprites were greatly expanded in height for the final game.
The same comparison image of the early sprites as redrawn from Gary Winnick's notebook and the final versions, now with aspect ratio correction applied. The proportions of the early sprites look a bit better than they do in the previous image.
A piece of concept art from the production of Maniac Mansion that was posted by Ron Gilbert on his blog. The image shows a printout of a game background with a character sprite visible, and a hand-drawn concept for the GUI above and below it. There's just one line of text at the top of the screen, as in the original Commodore 64 release. The GUI concept below the background is very much based on the UI in Labyrinth: there are two scrolling lists, with the left-hand one listing verbs, and the right-hand one showing the inventory. Not all of the verbs (or presumably items) would appear on screen at once. At the very bottom of the GUI, all three character names always appear, to allow character selection. The background art is an early version of the mansion porch exterior. The grate leading under the house is absent, and four windows are visible on the right side of the front door, where the final game only has three. The front doorbell is also missing. An early version of Wendy's sprite is standing in front of the door; this version is notably shorter than in the published game.
