Spot on Nino, H.R. Gigers work rocks. It is said he wasn't very happy about the rip-off when this pin came out.

As Quoted from the talented Mr. Giger

"Some stuff is a direct rip-off, some of it not so direct, but it's his mentality. It's all stuff that he did first. After the first Alien movie came out, the Bally Pinball Company made an Alien pinball machine without even asking him. When he tried to make an issue of it, they gave him two pinball machines."
