William Nicholson: Queen’s College. Lithograph from Oxford Colleges series issued by the Stafford Gallery in 1905, with their stamp lower right. 38 x 53cms. Signed & numbered no.15 by the artist lower left, but signature badly faded. Campbell 137.  Stuck to card. The limitation of the signed copies is not known, but the  numbers I have had through my hands are 5, 10, 11 & 15, which suggests to me 20 – 25.
