Large Box with people inside

This unique box was made by an innovative carver in Nahuala, Guatemala. He has made this functional box in the shape of a house. When you open the roof you see a platform representing a bed with a pregnant woman lying upon it. Next to her, is a figure kneeling, presumably praying. They are both dressed in the traditional Mayan dress of the village of Nahuala. The figures are movable. Also, front door opens. A rather large box and very unusual piece of folk art. 18 1/2" long x 9" wide and 7" deep.
