A study for the head of Iseult for the stained glass cartoon of 1862 which was subsequently over-painted into the watercolour "King Mark and La Belle Iseult" now held in Birmingham Museum and Art Gallery.
One of three drawings for the stained glass design 'King Mark and La Belle Iseult' also in Birmingham's collection. The drawings were studies for a series of thirteen stained glass designs illustrating the Story of Tristram and Iseult as told in Malory's 'Morte d'Arthur'. The windows were commissioned by a Bradford merchant, Walter Dunlop, for the decoration of the entrance hall at Harden Grange, near Bingley, Yorkshire, and are now in Bradford City Art Gallery.
