This is the first edition of סִדּוּר תְּפִלַּת מַצְלִיחַ Sidur Tefillat Masliah (Libro de Oraciones) (1974), a bilingual Hebrew-Spanish nusaḥ Sefaradi prayerbook compiled and translated by Rabbi Meir Matsliaḥ Melamed (1920-1989). As no Hebrew type with vocalization and cantillation marks was available to printers in Brazil, where Rabbi Matsliaḥ first began compiling prayerbooks, he developed a process of reproducing the liturgy from images of older siddurim and, occasionally, typewritten text. Rabbi Melamed’s translation appears to the sides of these images and his commentary underneath. This Spanish edition was preceded by a bilingual Hebrew-Portuguese edition published in Brazil in 1966. . . .
