In the Sèvres factory archives, this shape is referred to as a 'vase C de 1780' and a 'vase Paris'. Its design is attributed to the head of the soft-paste workshop Jacques-François Paris (or Deparis).
As noted by the gilder and by the Mintons Shape Book for this pair, the correct shape number at Mintons for this form is no. 469, 'Vase with Perforated Chain Handle'. The Mintons Shape Book entry of January 1904, lists the present pair as titled 'Prisoner' and 'Escape'.
