As Advent begins, the Holy Family is on the mind of many Christians. Now, Jesus, Mary and Joseph can also be on their envelopes.

The United States Postal Service has released a Holy Family stamp in time for Christmas cards and other mail. The stamp features an image of Joseph leading a donkey carrying Mary and the baby Jesus through the desert.

Officials from the USPS and state and local government came to the Presbyterian Center today to unveil the stamp, which was officially revealed at Washington National Cathedral in October. The stamp is a Forever stamp, meaning it can always be used to mail one-ounce letters regardless of increases in postage.

The stamp “marks the history of a family who changed the history of the world,” said the Rev. Gradye Parsons, stated clerk of the General Assembly.

Louisville Mayor Greg Fischer named Dec. 3, 2012, Holy Family Day for the city.
