Rebel Blockade Runner: Here it is, one of the most famous (and rarely seen) of the unreleased toy prototypes. It appears to be a completely plastic toy and not a cardboard mock-up. This is an overall view, but other details were photographed as well. This would have been part of the Return of the Jedi line but something kept it from being a reality. You can judge the scale of this toy by comparing it to the Luke Bespin figure poised by the radar dish. It surely would have been a fantastic toy, especially when you read all of its functions:
