Cupid letting a bird out of a cage probably dates from June 1892. It is a design for a stamp for the proposed publication of quatrains called 'Récréations Postales' by Stéphane Mallarmé (1842-1898). Whistler approached both William Heinemann (1863-1920) and Osgood, McIlvaine & Co. on Mallarmé's behalf but the project fell through. He wrote to Heinemann, 'Think what a pretty book - say for the season - Christmas or autumn whenever it is - With an arrangement to recall the Envelope! - and think what pretty things might be made out of the stamps!' 1

This is a design for the stamp on the cover, found in section IX of the manuscript for Recréations Postales in Glasgow University Library.
A cover designed by Mallarmé is in the form of an envelope, inscribed 'Récréations/Postales/de/ Stéphane Mallarmé‚/ JAMES R.OSGOOD/ LONDRES McILVAINE & Co/ Editeurs.' (175 x 214 mm, the flaps cut by hand irregularly. 2
It is possible that this is by Beatrice Philip (Mrs E. W. Godwin, Mrs J. McN. Whistler) (1857-1896). She drew a series of studies of cupids, one of which, posting a letter, appears to be a design for Récréations Postales. 3
It was not exhibited in Whistler's lifetime.
