![]() The box is lined with pink paper and contains three folded sheets of paper and a handmade pink envelope.  | 
    
 The boat has a slit so that the travelers can be slotted into it during their journeys.   | 
    
 One of the folded sheets is the instructions for three problems, one contains the pieces for the Fifteen Turks and Christians puzzle, and one contains a 4th puzzle - The dissected Cross .   | 
    
 The box is a fine example of early Tunbridge ware and was made in Tunbridge Wells; however both the box label and River Crossing figures were, we suspect, printed in France.
