I received Canadian cover dedicated to Year of the Rat and sent of first day of issue. The Rat is the first of all zodiac animals. According to one myth, the Jade Emperor said the order would be decided by the order in which they arrived to his party. The Rat tricked the Ox into giving him a ride. Then, just as they arrived at the finish line, Rat jumped down and landed ahead of Ox, becoming first. In Chinese culture, rats were seen as a sign of wealth and surplus. Because of their reproduction rate, married couples also prayed to them for children. This is cover is designed by sender and you can see historic propaganda poster for eradication of rats in Alberta!
