Twenty Love Poems and a Song of Despair (Veinte poemas de amor y una canción desesperada)

This title is overwhelmingly encountered in later Nascimento/Losada Spanish printings and in modern paperback reprints (Losada, Cátedra, Seix Barral, etc.); none of these are the first edition. No prominent U.S. book-club edition exists for the original Spanish work. For the English Merwin translation, watch for later Cape reprints (including the "Cape Editions, 38" series printing), Penguin Twentieth-Century Classics and Penguin Classics dual-language editions, and Chronicle/New Directions printings — all later than the 1969 Cape/Grossman first. The commonest trap overall is a genuine early Nascimento Spanish copy that is actually the 1932 revised edition rather than the 1924 first.
