I would agree, Dive. Like its black'n'tan predecessor, it was a very bold and strong corporate image,way ahead of its time.
Fifty-odd years on, black'n'tan (or supertrain) liveries would still look well on, say, an ICR - or even a 2600.
The Enterprise livery(ie's), by contrast, don't have the same enduring effect, and the lime & navy, or 2-tone green of the dreadful 29's is worse.
