This engraving is from The Art of Figure Drawing by Thomas Herbert Maguire, published in 1869 by Winsor & Newton.
It was a well known and authoritative book of the time cited often in the literature including; A Supplement to Allibone's Critical Dictionary of English Literature, Catalogue of Books Added to the Library of Congress, Supplement to the Universal Catalogue of Books on Art: Compiled for the use of the National Art Library and the Schools of Art in the United Kingdom.
It contained 30 lithographic plates, some tinted. I don't know, but from appearances it could have been influenced by Chapman's American Drawing Book (see the post below How Harry Cook Learned to Draw).
I found one reference to Mr. Maguire which listed him as a historical and portrait painter, and also as a designer of music title drawing, which would explain his evident skill at engraved illustration. Examples of his portraits can be seen at the National Portrait Gallery Website.
