Third Grade Velocity Studies (Thompson, John Sylvanus)

This work is likely not in the public domain in the US (due to first publication with the required notice after 1927, plus renewal if published before 1964, or "restoration" under the GATT/TRIPS amendments), nor in the EU and those countries where the copyright term is life+70 years. However, it is public domain in Canada (where IMSLP is hosted) and in other countries (China, Hong Kong, New Zealand) where the copyright term is life+50 years.
