Nice collection there! I really like that Death Star that's mounted on the ceiling... a very nice touch! Thanks for sharing pictures of your collection with us.
I found that death star piece at a flea market, it is actually two pieces that screw together. I sold the other half to a friend at artoos news. I got it for 2 bucks. I just thought it looked cool, I am not sure exactly what it is, but I think it is some sort of food promotion item, maybe Taco Bell. Not really sure though.
