"The Smallest Dictionary in the World"! The case is about 1 x 1.5" and has a small magnifying glass within and a loop to wear it as a pendant. The book is in very good condition, especially considering how delicate such a small binding is, and the red colouring still very bright and unblemished.
Though it is undated it is most likely to be printed in the second half of the 19th century. A lovely object and curio.
