According to Franciszek Maksymilian Sobieszczański's "Historical Information on Fine Arts in Poland", Volume II from 1849, the local museum in Brno in todays Czechia, had in its collection "a beautiful basin with an ewer, all enamelled in flower stripes, which was given by John III, among other items after relief of Vienna, to Emperor Leopold I, later in Empress Maria Theresa's study, given by her to the Princes of Solm, and few years ago offered to the Moravian Museum, is today kept in Brünn with athentic documents of its provenence" (page 326). The basin from original lavabo set was most probably lost, while enamelled picher in flower stripes is in the collection of Moravian Gallery in Brno (inventory number U 24136). Despite being dated to the second half of the 17th century on the museum website, it was most probably created during Yongzheng Period (1723-1735) for Persian or Ottoman market, hence any connection with John III Sobieski (1629-1696) of Poland can be excluded.
