According to the Library of Congress, 'The arrangements in Trafalgar Square delighted Whistler, and Joseph Pennell was so delighted with Whistler's sketch that he sent it to The Daily Chronicle, in which paper it was printed, June 18, 1897, Whistler making a few changes and signing it with his butterfly.' 1

By the time it was published Whistler had indeed added several details, such as supports for the stands on the right, shadows at the bottom of the stands, and a butterfly with a long barbed tail at right. The text under the sketch had been removed, and 'London in her glory' was added at upper right, while the signs at left and right were altered, that at left now reading 'Maple Apply' and at right, 'STEVENS / contractor'. 2
There are both vertical and horizontal folds in the sheet. The paper has darkened and has a slight beige tone.
See further details in MacDonald 1995 (cat. rais.) [more] (cat. no. 1507).
It was not, as far as is known, exhibited in Whistler's lifetime.
