Yes, the double crab Marco found might be unique outside of the context of mirrored constellations that are consistent for several signs, I have to check.
More on multiples...
Every time I look at my files I remember something I've forgotten (it's a lot of zodiacs).
For example, Royal MS 2 B VII has multiples...
but they appear to me to be very specific. As far as I can tell, the reason for the multiples (Aries, Taurus, Capricorn, Sagittarius) is because they are herd animals. Since Sagittarius is part horse, that would make it a herd animal too. There appears to be a lioness next to the lion (strangely drawn). Lions are pack/pride animals, so perhaps were also considered a "herd" animal by the illsutrator. The others aren't replicated. There are 5 sheep, 3 bulls, 2 goats, 2 centaurs. The rest are single. I almost expected Pisces to be replicated, but the marine critters are not.
