Count Karoly was a guest at Chatsworth, the residence of the Duke and Duchess of Devonshire, on the evening of October 20, 1832. Among the attendees was the young Princess Victoria, who would later become Queen Victoria. After dinner, a charade was performed where Count Karoly took on the role of Bluebeard. Following the visit, as Princess Victoria continued her Royal Progress in her carriage, she sketched a portrait of Count Karoly from memory in his Bluebeard costume. This sketch is now part of the Royal Collection Trust. One might wonder if Count Karoly was proudly wearing his Breguet watch during his stay at Chatsworth.
