The caricatures, which date from about 1870 to 1932, the year before the artist's death, depict many celebrities of the artistic, musical, and literary worlds, by whom the house of his father, Alfred James Hipkins, the musical antiquary, was much frequented.

At the beginning of MS.2919 is a biographical notice of Hipkins by his sister; there are portraits of him by her, 1879, at the beginning of MSS.2923-2924, 2926; and his own caricatures of himself appear in MSS.2919 (page 25), 2921 (pages 6-7, 45), and 2922 (page 5).

The volumes also contain some letters addressed to Miss Hipkins, and sketches by Lawrence Alma-Tadema, Sir George Henschel, and others.
