[Lady Pembroke, object of the affections of the insane King George III.] Autograph Letter Signed (‘Eliz: Pembroke’) to her nephew the Hon. George Ellis, having received permission from the Queen to allow him to ‘cut a dash abroad’.

See her entry in the Oxford DNB, which states that ‘During his periods of ‘madness’, George III imagined that he was married to Lady Pembroke. Apparently, 'his infatuation went back to the days when he was only seventeen and she, of the same age, was Elizabeth Spencer'. The king went so far as to make 'her handsome offers if she would be his mistress.’ [...] In 1804 the king suffered another attack of dementia and again announced his desire for Lady Pembroke. This situation aroused some amusement among younger courtiers since she was by this time almost seventy years old.” 1p, 12mo. On recto of first leaf of a bifolium; the verso of the second leaf, the lower part of which is torn away, carries her seal in red wax, and the address in her autograph: ‘The Honble. / George Ellis / Ld: Vist: Clifden’s’. In fair condition, lightly aged and worn. Folded twice. The letter, written in a stylish hand, reads: ‘My dear George, I have done the business for you, & Her Majesty was most gracious, so you may make yourself fine & cut a dash abroad. It is sad you cannot come & dine here. I shall be in Town on Monday Evening, should you have any more commands for me. I am / Dr George Yr: Aff: Aunt / Eliz: Pembroke | Saturday morning. 29th. June.’
