Philippe de Champaigne's "The Annunciation"
The 25th is the celebration of the annunciation. Check out the March liturgical folders at Familia Catolica. You can make a liturgical folder for the annunciation using this printout of the Angelus, and the printable coloring page here. (Click on "coloring pages" and then you'll see the Annunciation as one of the coloring pages.)
