Catalogue des pierres gravées antiques de S.A. le Prince Stanislas Poniatowski ([1830?]-1833): I.140
Christie's, London: 1839-355
Prendeville, J.: Explanatory catalogue of the proof-impressions of the antique gems possessed by the late Prince Poniatowski and now in the possession of John Tyrrell, Esq. (1841): 90
Catalogue of A Rare Collection of Antique and Medieval Gems, (...) for the Charity Organization Society (...) of NY; Tiffany, 10.-16.3.1902: lot 954
Comments: CHRISTIE'S: CHALCEDONY. There seems to be some confusion in the 1839 Christie's catalogue about T90 and T91: only one entry was made although both are listed in the pierres gravees and were bought by Tyrrell.
