English: After inquiries to the source website, I was informed by site representative Brett Langston that while precise information on the photographer and date of creation were not available, it was the opinion of the site that the photo was public domain and therefore not subject to any copyright restrictions. Also, the subject of the photo, Modest Ilyich Tchaikovsky, died in 1916 and the photo apparently portrays the subject considerably before that time; therefore, it should qualify as public domain under PD-OLD and PD-1923.
