The author died in 1919, so this work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 95 years or less. This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1923. Please contact me if you would like a change in scale. I am always happy to accommodate change requests. If this design is not perfect for you, I have several other Ernst Haeckel inspired designs in my Vintage Drawings Collection.
