Costumes from the 1980's are easily recognizable and were a huge part of any kid's life growing up in the 70's and 80's. The well known Ben Cooper Inc. company began making Halloween costumes in the late 1930's and within a few years became a prominent manufacturer for Halloween costumes. By the 1950's their catalog included Disney characters, superheroes and even Presidents. By the 1970s, the company was one of three top Halloween costume companies - the others being Collegeville and Halco.
The rest of the "costume" actually was a plastic-vinyl smock that slipped on over your clothes and tied up in the back at the neck. It often had designs printed on the front, usually with the name or the picture of the character. The smock, as you might imagine, was quite uncomfortably hot and slightly cumbersome to wear. The smell of the vinyl alone was enough to cause hallucinations. However, we kids persevered through the torture and proudly marched on down the streets to trick-or-treat as our favorite character. This is all we had and it was obvious the company went to great lengths to be the top costume retailer. While almost all characters were represented in the familiar Ben Cooper costume line - like He-Man, Freddy Krueger, Superman, The Smurfs, Wonder Woman, Cabbage Patch Kids, Batman, Lone Ranger, Jem, Star Wars and Disney - two characters never did make it to plastic costumes.
While it is unfortunate that Roger and Jessica Rabbit didn't get to officially join the ranks of many characters created into vinyl Ben Cooper 80's costumes, we at least have The César Group's version - which will keep you awake at night or haunt you in your dreams!
UPDATE: It appears there was a Roger Rabbit costume created by Ben Cooper Inc., however they are extremely rare to find now. Here are three photos I saved a long time ago of the costume in and out of the box, in pretty much mint condition. There have been no photos of any Jessica Rabbit costume by this company, but it is more likely she was not made into a costume.
