      Dear Jo: -
 
      
 
 
I know how much you helped to make the books and frames for 
      the Royal visitors a real success, and I am very grateful to 
      you for your fine cooperation and assistance.
 
      My best wishes to you and I hope to see you one of these days.
 
      
 
 
Very sincerely yours,
 
      
 
 
Miss Jo Coffin,
