The jug has some similarities to a small group Worcester porcelains painted with birds attributed to an 'I Rogers', which is based on the documentary Worcester mug in the British Museum, London, inscribed I. Rogers/ Pinxit/ 1757, reg. no. 1959,1103.1. Hugh Tait in his article 'James Rogers, A leading porcelain painter at Worcester c.1755-65', The Connoisseur, April 1962, argued that these pieces were by a James Rogers who exhibited at The Free Society of Artists in 1765, when his address was given as 'Dobson China Shop, St. Martin's Court, Leicester Fields', but as yet no contemporary documentation has been discovered linking John Rogers to the painter of the British Museum mug, 'I. Rogers'.
Among the rare pieces of this size and exquisite decoration attributed to 'I Rogers', a 'Dutch Jug' of the same size as the present lot was with Brian Haughton, London, illustrated in their catalogue Splendour of a Golden Age, Eighteenth Century English Porcelain 1745-1770, London 2004, p. 33, no. 26. A smaller jug (20.2 cm high) attributed to Rogers is in the Henry Rissik Marshall Collection, Ashmolean Museum, Oxford, acc. no. WA1957.24.1.473, illustrated in Dinah Reynolds, Worcester Porcelain 1751-1783, Oxford 1989, pp. 26-27, pl. 9. A further smaller jug sold at Bonhams London, 1 May 2013, lot 81, formerly in the R.
