Concept Spacecraft - 1990s

As the world prepared to party like it was 1999, speculative spacecraft model kits continued to drip into the market like some kind of perverse Chinese water torture.  But when they did appear, these models didn't come from China.  They cane from the newly "freed" Russian Republic and from Germany.  America, still the global leader in actual manned space flight, decided to stay on the sidelines when it came to marketing miniatures of even grander Things to Come. Fortunately, a few garage kit companies also stepped up to provide kits of unrealized spacecraft concepts from this period.
