Oxford: Emberlin and Son, 1890 (but 1907). Stiff card wraps. Fine. Item #20185 .
The Letter-Writing pamphlet is 4 by 3". 39pp. Publisher's ads appear on pages 36-39, and the last page is blank. Even though the reverse of the title page states "First Published 1890", this is clearly published about 1907 as the list of Lewis Carrolls' ends with "Feeding the MInd". See Crutch, 223d,(1).
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 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.
