This guy has a website that has tons of pictures of bootleg toys including a SW section.
There are some really interesting rip off SW toys in there. Honestly, even though some of them are easily identifiable as bootlegs I would probably pick them up if I saw them in a store. Some of the attempts to create DV or a Stormtrooper are hysterical and would make great shelf filler.
Some of the items in his collection might actually be legit SW stuff though. I believe the following are real...
I have(had) the Queen and Anakin heads but am unable to find them now to verify that they are in fact the same. These heads came inside a semi-clear bar of soap and would be freed once you used the soap. He doesn't really say where he bought them other than they were loose. If he bought them at a flee market or something that would explain why they were loose since the previous owner probably used the soap to get the heads out.
To be fair, he does question whether or not they are real at the end of the page.
About the soap though, these has to be one of the dumbest ideas. Using the soap is fine until the small HARD plastic head starts to poke through. Next thing you know your scrapping the crap out of your skin as you rub yourself down with the bar. Ouch! I learned that the hard way.
