Many companies tried to profit from the popularity of Star Wars by making bootleg figures. One unique approach was by a toy train company, Model Trem. This Brazilian company produced bootleg figures made out of lead. These figures are extremely rare and finding the original packaging is even more of a feat. One of my items on my wish list is the original packaging for a Model Trem Luke Jedi figure.
More information about the Model Trem bootlegs can be found at The Star Wars Collectors Archive which is where I borrowed the last image from.
