I saw one of the Sideshow 1:1 bust years ago. It is great looking. I was at a small comic show looking for anything ALIEN when these two guys invited me to see their ALIEN collection. They lived near by. (Today I would never go to a strangers house alone, Oh youth
)
Their collection was impressive not only did they have the Sideshow bust. They had the vintage toy movie projector which I got to watch.
And various other ALIEN items. It really was a treat for me as most of my collection was not of that quality.
