1978 Superman Slide Tile Puzzle

I recently purchased this bit of my childhood late in 2011. I remember this was my 'busy' toy when the family had to take a long drive. My mom would mix up the tiles and I would try to reconstruct Superman to his chain breaking glory.

I have yet to scramble the tiles on this puzzle, and probably never will. This I actually won from some seller in the UK. Even with the shipping it was under 10 dollars.
