Probably detached from one of four issues of Whiggeries and waggeries, London : William Strange, 1834. This publication reprinted wood engravings by Robert Seymour, Robert Cruikshank, and others which had previously appeared-- with different captions-- in Figaro in London, also published by Strange. The identical image appeared in Figaro in London, no. 22, 1832, with the title Wetherell as a clown.
Wetherell, grotesquely knock-kneed, as a clown, blows a trumpet.
