In Volume I of their work at p. 235, Coyish and Hayward suggest that these designs appear to be part of a multi-pattern service and note that one example has been found with the impressed mark “Improved Stone China”, suggesting Minton as the maker.
 
To date, 14 design variants have been found according to Coyish and Hayward in Vol. II of their work at p. 130. However, the Transferware Collectors Club data base shows 18.
 
Some of the central designs of the series appear to be derived from Pinkerton’s “A General Collection of the Best and Most Interesting Voyages and Travels in All Parts of the World”. Published between 1808 and 1814.
