The Doctor himself pouring out his whole soul for 1s. Satirical etching by John Boyne, 12 February 1783 (British Museum 1868,0808.4926).

Wikimedia Commons reproduction of a British Museum satirical etching by John Boyne, published in London on 12 February 1783 by R. Rusted (accession 1868,0808.4926). The print shows the lecturing figure (identified by the British Museum catalogue as Dr. James Graham) raised above an audience, with the title 'The Docter himself Pouring out his whole Soul for 1[s]' mocking the shilling admission to Graham's lectures and the publication line reading 'London Published... Feb 12 1783 by R Rusted'. The British Museum catalogue notes the print references Graham's 'Lecture on the Generation Increase and Improvement of the Human Species' and his Celestial Bed. The visible image clearly shows a single standing speaker on a raised platform addressing a crowd of well-dressed onlookers; the identification of the speaker as Graham rests on the British Museum / Wikimedia catalogue record.
