Riddles riddles

 My ex-husband was helping out at a house renovation when they were tearing out some walls.  This book was found inside one of the walls!  It's a Dr. Suess beginner book called Bennett Cerf's Book of Riddles with drawings by Roy McKie.  The copyright date is 1960.  A very charming book just perfect for my oldest son, Jacob, who is learning to tell jokes.  He is really bad at it but fortunately he's getting better.  This is full of simple question and answer riddles that he's sure to be able to memorize and share with his friends.

 

 I really like the riddle below.  The previous owner wrote a name next to the illustration.  Perhaps Mary is her sister?
