A lilac and white jasper example of this shape with a pierced cover, also decorated with the amorini design is illustrated in Robin Reilly, Wedgwood, Vol. 1, p. 626. fig. 941, where the author catalogues it as "extremely rare" and states that the bas-relief work has been attributed to John Flaxman on the basis of the subject matter, but that no evidence has been found to support this. Reilly further notes that the design is after "an octagonal cinerary urn, formerly in the Albani Collection, now in the Capitoline Museum and would certainly have come to Wedgwood from an atelier in Rome." See ibid., p. 627, fig, 941A for a wax model of this design.
