It seems unlikely that Cadogan doodled cute bunnies upside down on the letter. The decorative element is not handled in the usual style of either Whistler or his wife Beatrice Philip (Mrs E. W. Godwin, Mrs J. McN. Whistler) (1857-1896). However, both experimented with different styles. The economy of line and element of wit suggest it could be by Whistler. It is possible that the drawing was a visual pun on the name Birnie Philip: Beatrice's younger sister Ethel was nicknamed 'Bunnie'.
The sheet has been torn from a larger, folded sheet of notepaper, the torn edge being to the left of the embossed arms. There are two pinholes at top left, probably caused by pinning it to other documents. The sheet has been folded into four. The drawings are on the verso. The letter was written with a medium square nib, the ink, being slightly watery, has taken something of the tone of the paper. The drawings are in a similar ink and nib, but done upside down.
There is no record of any exhibition.
