Great for skeptics and paleo-enthusiasts! The _Trilobites had no astrology_ series features emblematic trilobites in the style of astrological sun signs - while pointing out that the position of the stars 500 million years ago would have rendered astrology moot. Each design has an astrological symbol incorporated into the trilobite.
Stars may not affect your life through astrology, but these shirts and stickers are a great conversation starter. Look for the whole series, and soon: a posters and calendar!
