This was the first, and as far as I know, only plastic model of Hubble ever to be sold.
The model is in approx. 1/72 scale (1/70), making it a good size reference against the Revell or Monogram 1/72 Shuttle Orbiter.
This model is detailed in "stowed" or launch mode, as the Shuttle would have taken it into orbit on STS-31.
