Little Boy Bedtime Prayers or 1st Communion Plaque

The sweetest little wood (walnut?) plaque of a baby boy kneeling at prayer on a cross. I don't know what sort of metal it is. It needs just one screw on back (up close, photo 3), not included. Measurements are shown in photos 4-5. All angles shown in photos 7-10. Light imperfections shown in photos 13-15, a light mark on the lower right-hand side, photo 14, and photos 13 & 15 show what appears to be glue that leaked in the manufacturing process that is barely discernible w/naked eye. So sweet!
