Portrait of John Lubbock, 1st Baron Avebury

Half-length portrait of Sir John Lubbock, seated at his desk by a study window at High Elms in Kent. Lubbock holds the base of a compound microscope in his right hand and has a single lens magnifying glass in his left hand. There are specimens and an inkwell on the table. A bookcase appears behind him and Lubbock's wooded estate is visible through the window.
A specimen of his signature is found under the portrait.

The portrait was printed after an etching by painter Theodore Blake Wirgman drawn from life, as a supplement to The Graphic, under 'Celebrities of the Day'.
