Vintage Lego Space Minifigure

In relation to the upcoming May 4th, as well as Star Trek hitting theaters soon-ish, here's some Space Lego minifigures!

Lego was never one to shy away from trends, and what was more relevant in the late 70s and early 80s than family-friendly sci.-fi? 

And they have kept at it ever since. The guys below can be dated from early 80s to the early 90s. Notice how the logo evolves from the earliest (yellow, far right), to the blue one. The yellow one didn't actually come with the motorcycle styled helmet. He came with the one that more closely resembles a bucket. But at some point in history, Lego lost the mold to that helmet. And when ever they re-issue the vintage space guys, you'll see this new styled helmet.

The old helmet can be seen on this awesome little guy:
