Oxford: Emberlin and Son, 1890. First edition. Stiff card wraps. Fine. Item #20185 .
The Letter-Writing pamphlet is 4 by 3". 39pp. State first edition. Publisher's ads appear on pages 36-39, and the last page is blank. This state is not described by Williams, else it bears the earliest possible date of 1890, with the 'first published, 1890' statement on the verso of the cover
The stamp case bears the statement on the rear: "Invented by /[Cheshire cat smile] /Lewis Carroll/MDCCCLXXXIX". The case into which it slips is the second state (Williams 194.1) with the publisher's imprint above the Cheshire cat.
This is a very nice set with hardly any trace of wear and only normal signs of ageing. The outer envelope is not present.
