Lamb’s Quarters or White Goosefoot, Bertha E. Jaques (attributed to), 1910
Known primarily for her etchings, after 1900 the American artist Bertha Jaques also made numerous photograms of wild flowers. Jaques placed the flowers on a sheet of cyanotype paper, which she exposed to light and then developed in water. The flower thus showed up as a white silhouette against a blue background. The simplicity of Jaques’ imagery gives it a great power of expression.
