My thanks to Forums member jguss for providing the following information:
"All I can tell you is that Amilcare Lusuardi was a resident of Turn, Italy; his business was located at 73 Corso S. Maurizio. Lusuardi applied for his US trademark on Sept 5, 1923. In the application he stated the TM had been used by him in his business since Feb 1, 1921. The same TM was registered in Italy on May 16, 1923. Lusuardi, along with a partner named Aristide Falco, was apparently a serial inventor of other things beyond tobacco pipes (registering manometers, etc). Offhand I don't recall seeing his name in my review of US tobacco trade journals from the early 1920s. My memory could be faulty, or equally likely he was an exceedingly minor player in the industry."
