No place, no date [1820s-1830s].
 
Single leaf, small oblong card (approx. 65 × 175 mm), 4 lines written in brown ink, signed A. I. Byron; cut from a larger letter, old folds, light staining and remnants of mounting to versos, with a contemporary red-ink identification “The wife of Lord Byron”.
 
A brief note from Lady Byron and addressed to a close friend or family member. “I have been in Town some days with my father—Write in a leisure moment, and perhaps not very intelligibly—but you will make every allowance & believe me, Yours most affectionately, A. I. Byron.” 
 
A scarce autograph of an historically significant figure: the moral and intellectual counterpoint to Byron, and the mother of Ada Lovelace.
