And a picture without minifigures:
I compared it with the TV Show so you can see how similar it is. Here's the Front and Back comparison:
and the Top and Side comparison (yea, I know, the top of mine is a whole lot smaller then the TV series one, but, there is only so much one can do with a limited collection ):
More pics at my Flickr.
C&C are welcome, as usual
