After attending art school in Melbourne around 1921, Ruby learned to execute a more 'classical' style of watercolour painting than her earlier detailed and whimsical works. She had exhibited some watercolours, etchings and pencil sketches in Rockhampton in 1973, but the majority of her paintings were in storage, and were discovered by her niece Heather Stewart just prior to Ruby's death in 1977. This watercolour is one of the paintings that Heather discovered in storage, and was able to get Ruby to sign before her passing. Ruby was passionate about supporting the Arts in Central Queensland, and had donated works and funding to help establish Rockhampton and Biloela Galleries. Her descendants continue this legacy. Ruby's works are now held in Rockhampton, Gladstone, Banana Shire, and Toowoomba Regional Galleries, as well as in a number of private collections in Qld and interstate.

- Additional Ruby Campbell Watercolour of Tree Trunk
Trees were a very popular subject for Ruby, and were depicted in her etchings, pencil drawings, and watercolours. This particular watercolour is one of a pair showing the detail in the trunks of large gum trees.
