OK, I went through the back issues section (it goes back to '86) and found this:
January, 2000: Defiant from
Star Trek
September 1997: Voyager from
Star Trek
May 1996: Narcissus from
Alien
February 1995: Survey-class vessel from
Star Trek
March 1989: Klingon Bird of Prey from
Star Trek
August 1988: Whispership Interceptor (original scratchbuild)
January 1986: Speeder Bike from
Star Wars
So there you go! Over 20 years of FSM covers, SF gets seven of 'em, with
Star Trek getting the lion's share at five.
I find it very interesting that a
completely original scratchbuilt SF subject got a cover, in August of '88! Equally surprising is that
Star Wars only got one!
So, were there any other
Star Wars covers prior to this? Or any other SF covers?
It was good to see that the Space Shuttle got two covers over the last 20 years!
