A line drawing can be found on p. 5 of The Art Journal Illustrated Catalogue of the London Exhibition of 1862. The present pair were most likely painted by Charles Ferdinand Hürten (Cologne 1818-1901 England). Hürten began his career as an 1858 Paris Exposition artist for Sèvres before moving to the Copeland factory in 1859, where he stayed until his 1897 retirement. A frequent exhibitor, the 1874 Art Journal reporter observed that Hürten 'has no superior in flower painting... his perfect feeling for all the beauties of texture and colour in his favourite subjects is sufficiently obvious. He makes us see he is as much a florist as an artist, and as true a student of form as of colour.' For a nearly identical signed example, see Christie's, London, 15 July 2008, lot 167.
