Shape 99 is recorded in the Minton Ornamental Shape Books as Vase, Sévres Eared and as being made in three sizes. In addition, it notes that examples were produced with majolica glazes. This vase form was entered in the estimate book in February 1839, an early date for wares of this style. Also see Geoffrey A. Godden, Minton, Pottery & Porcelain of the First Period 1793-1850, New York, 1968, fig. 118 for a similar blue Celeste example.
