(Esperanto), a 1922-23 collection of postal cards, all addressed to 'Sinjoro Colin Unwin' in Fremantle and all written in the nascent 'Universal' language of Esperanto. Unwin's correspondents were from Rotterdam, Radom, Genoa, Krakow, Wilno, Warsaw and Bialystok. (8 items). Esperanto was created by Polish ophthalmologist L. L. Zamenhof in 1887. His goal was to create an easy and flexible language that would serve as a universal second language to foster world peace and international understanding, and to build a 'Community of speakers', as he believed that one could not have a language without such a community.
