Gertrude’s paintings and illustrations consisted of mainly portraits, interior genre scenes, and literary subjects, all done in watercolor. She was given the opportunity to exhibit at the Royal Academy and the Royal Institute of Painters in Water-Colors where she presented Youth’s Spring-Tribute. This graphic watercolor illustrated Youth’s Spring-Tribute, from a sequence of poems, The House of Life, by Dante Gabriel Rossetti, in 1881. This watercolor was then reproduced in a publication of an Edwardian birthday book in 1905, The Beautiful Birthday Book, replicating watercolors by Hammond.
