If you would like to see Benny carrying the umbrella, follow these directions: Trace the pictures, cut out and paste one on each side of a cardboard disc the same size. Place them so the corresponding letters are together-—the two A's at the top and the B's at the bottom and the dots at the sides are together. Thread a darning-needle with string and run it through the black dot at one side of the disc. Make p loop and tie the ends together about three inches from the edge of picture. Cut off surplus string and repeat at other side of picture. Hold the ends of strings between first fingers and thumbs, twist them back and forth, and you will see both sides of the disc at once.
