Things weren't always this big and bold for Star Trek enthusiasts. Three years after the original series ended, the first convention was held in New York City in 1972. Four years after that, a convention was held at the Northglenn Mall near Denver, Colorado, that lives on in this charming-yet-awkward video recently discovered by the website Boing Boing. 

The video features host Terry McCoy showing us around a convention floor filled with Star Trek paraphernalia, cosplay and a few celebrity appearances. 

The clip starts off innocent enough, with host Terry McCoy introducing himself to the camera. 

The special effects are a nice touch to the Super 8 film. We dig it. 

Wait a second, is that Leonard Nimoy at the table?

McCoy also encounters a man dressed up as a Caitian, who is none too pleased when McCoy asks if he's related to a Romulan or Vulcan. 

There's James Doohan giving a speech. We wonder how much Nimoy and Doohan got paid to make these appearances?

It's amazing to see just how far Star Trek conventions have come since they started in the 1970s. Check out the full video below - it's a charming mix of nostalgia and social awkwardness at its finest.
