This blogger loves the picture of a bookvan (mobile bookstore) in Lisbon (Belém?). It made the news in the summer of 2013, as it visited different sights to promote Portuguese authors among foreign tourists:
“In Cais do Sodré the tourists can meet O Memorial do Convento [Baltasar and Blimunda] by José Saramago. In Príncipe Real it is time for Eça de Queirós (1845-1900, Wikipedia) and his classic Os Maias [The Maias]. In Belém, to come across Fernando Pessoa and his Desassossego [The Book of Disquiet]. Translated into English, French, Spanish and German, the books by José Cardoso Pires (1925-1998, Wikipedia), Jacinto Lucas Pires (Porto, 1974, +info), Gonçalo M. Tavares and Miguel Torga (1907-1995, Wikipedia) are also some of those available in this van.” (Marta Spínola Aguiar)
