This is one of those old retro Lego spacemen! If you've ever played with your parents' old legos, you recognize this classic minifigure well. These guys were a whole lot simpler than modern legos, but they were still really fun to play with. Also, if you've seen the Lego Movie, you'll know that Benny was one of these spacemen. SPAAAACCEESHIIIPP!

A brief history of the figure/some facts:

• The "Blue Classic Spaceman" was released as a LEGO product in 1984.
  
• It was the last color of the class astronaut series.
  
• These astronauts were the first mini-figures to have printed-on textures.
  
• The helmet was often too thin, meaning that the chin-strap would often break.
