In animation, a “model sheet” refers to one of the many incredibly important reference images created by the shows main designers. Together, all of the various model sheets needed for an animated show make up a kind of style guide which is then used by all of the other artists involved in production. The main character designers at DiC were responsible for these model drawings which depict each of the Real Ghostbusters characters common poses, gestures and facial expressions. Model sheets also help maintain the style, colour and sizing of the shows characters, vehicles, accessories, weapons and locations in order to ensure continuity.
Every single company that produced Real Ghostbusters merchandise would have been supplied with similar images which were then given to the artists they employed. For example, the ones that I own are all copies which came from the advertising agency in New York that handled the commercials for Kenner’s toy line.
Promo Pilot Model Sheets
Below are some images of a few of the earliest model sheets ever produced (Dated between October and November 1985) which include artwork from character designers Gabi Payn, James Gallego & Marek Buchwald.
The prop model sheets are cool because they feature images of things only ever seen in the original RGB promo pilot like the Ghost plane piloted by the skeleton & the Stay Puft Marshmallow van which Slimer hijacks.
You may notice that unlike the rest of the team, Peter’s sheets are undated (the rest of them are from 1985). This is because he was completely redrawn by Gabi Payn a few months after the original promo pilot was produced (where he looks more like Bill Murray).
Prop Model Sheets
Syndicated Season Model Sheets (Courtesy of James Eatock)
Below are images of the majority of the model sheets from the first syndicated season (episodes 14-78). These are far more detailed than the ones shown above and include all of the different body turns and facial expressions for the characters as well as informative pages on the firehouse, Ecto-1 etc.
I’ve grouped the colour sheets together for anyone wanting to know the PMS (Pantone Matching System) colours for jump suits, proton packs etc.
Here are the black and white sheets from the syndicated season style guide which show facial expressions and poses for all the main characters. This gallery also includes some very detailed interior sheets for the various rooms of the firehouse as well as Ecto-1.
