"Be sure to get back for Rally Day. 'The heavens declare the glory of God; and the firmament sheweth his handywork.' Psalm 19:1." Rally Day is a special celebration held by some Protestant churches in September or October to promote family attendance at church services and children's participation in Sunday school. This postcard, which was used to remind church members (and astronauts, too, I guess) to attend Rally Day activities, likely dates to the 1960s when the Space Race was taking place.
