Open a different window each day of December to reveal a Christian image behind each one. These calendars have a picture and a Bible passage behind each window. They make great gifts from the church or Sunday school teachers. The back of each calendar leads young people on an 'Advent Treasure Hunt' each day with a question, a riddle or a fill-in-the-blank that is answered or filled in when you open the window on the other side. Calendars are 9.25' x 12.5'.
