Sketches of the journey to Alsace probably date from October 1858, and were drawn in a letter sent to Whistler's half-sister Deborah Delano Haden (1825-1908). The letter was started en route from Aix la Chapelle and completed and sent from Paris. 1

The relevant parts of the letters are as follows:
'How, after having hopelessly waited for an answer to my letter, during ten long days, Erneste and I … we then set off, with nothing but a blouse on our backs - [drawing of Whistler and Delannoy] ...
… how my wretched Parisian shoes got rid of a portion of their soles ... and a great part of their upper leather - [drawing of shoes] ...
… Shall I say that the man who gardes [sic] the life of his Emperor understood the neatness of my argument. [drawing, Whistler bribing a gendarme] ...
… my entré at the Café Voltaire on Sunday evening was of the most triumphant! - [drawing, Whistler and friends in the Café Voltaire] Comment! t'es pas mort! …' 2
Whistler and his companion Ernest Delannoy (d. 1869/1872) figure in the sketches.

Lively pen drawings are scattered through the letter. The ink shows through a little from the verso.
The letter, sent to Deborah Delano Haden (1825-1908), has not been located; part of it survives in a manuscript copy in Glasgow University Library and a photograph of part is in the Pennell Collection in the Library of Congress. 3
