 note = {We confirmed the portrait of Esperanto founder Ludovic Zamenhof in the
conservation activities of the material ,conducted in Miyazaki city, Miyazaki
Prefecture. In Miyazaki city, a portrait with almost the same composition is drawn by
EI-Q (Hideo Sugita).
　Therefore it was expected that this portrait was related to EI-Q and Miyazaki
Esperanto Club. As a result of photographing the sign drawn in the portrait with
an infrared camera for cultural property, it was confirmed that there was a high
possibility of being the signature of Atsushi Kawagoe as stated in Esperanto.},
