The Year of the Sheep (or Goat, as this is the same in Chinese) ran from February 2015 to February 2016. To celebrate this, Bee released this commemorative deck. Earlier years of the sheep were 1979, 1991 and 2003.
In the Chinese astrological zodiac, those born under the sheep are friendly, peaceful, and popular. The deck reflects this with a happy deck full of Asian symbolism. You will enjoy pointing out this symbolism to your audience as you're working with this clever deck.
