The collection consists of a sketchbook with drawings largely of churches, country houses, and other architectural subjects. It includes a few loose and pasted-in sketches at the back. There is a poem of unknown derivation under the first sketch in the book, preceded by an index to 62 sketches dated 1821-1824. Later sketches are pasted in or loose.
The collection consists of transcripts of poems with holographic revisions and notes; correspondence from Dowson to Henry Davray, John Lane, Charles Sayle, Leonard Smithers, and Victor Plarr; copies and typed transcripts of letters from Dowson to John Lane, Conal O'Riordan and Henry Davray, and of letters from R.H. Sherard to O'Riordan about Dowson, after his death.
The collection consists of 123 pen-and-ink drawings and watercolours titled: Sketches of the War : France/Belgium in 2 volumes and is dedicated in a pasted in letter: "To my Daughter Adele." The sketches vary from satirical cartoons to more detailed and naturalistic renditions. They are often accompanied by an ironic title and are often signed with the artist's initials, "J.M." The artist's satirical targets include the officers and high command of both combatant sides; the disjuncture between reported and actual events, and the death of civilians as a fact of modern warfare.
The fonds consists of four volumes of photographs, the first of which also contains drawings. The drawings commence in 1846 (done by family friend) and recommence in 1884 (done by JHA and friends). The final drawing seems to be 1890. The photographs cover the period 1884-1909. They begin in England and also cover Ireland, St. Helena, South Africa, and Scotland. Some have a military setting but some are scenic and social.
The collection consists of a woodblock and a signed pencil drawing of a "Mother and Child" (used as a Christmas card for the Peace Pledge Union); a collotype reproduction of a signed pencil drawing of David Pepler; a typed, signed letter to ? Henderson re: the Catholic Church and the Trade Union Movement, with a pencil draft on verso (illegible?); and eight signed engravings to illustrate Patrick Miller's "The Green Ship" (Golden Cockerel Press).
