General Tom Thumb was the stage name of Charles Sherwood Stratton (1838-1883). He was an American actor, singer, dancer and comedian. P T Barnum brought him to Europe for the first time in 1844, when he was six years old and just over two feet tall. He had successful seasons at the Egyptian Hall in 1844 and 1845. The engraving is attributed to A.H. Payne, 1847, after T.H. Shepherd.
The second image shows what looks like a page torn from a book which includes the same Egyptian Hall engraving, as well as one of the Burlington Arcade, Piccadilly. The book from which this page comes is not known.
