The "Book of Love" is the first publication of the Núcleo de Estudos Marcello Grassmann, whose collection contains unpublished works by artist Marcello Grassmann presented in this artistic book with texts by friends Leon Kossovitch and Denis Bruza Molino in addition to a text by Ana Godoy, the result of interviews and correspondence with Marcello's companion, artist Zizi Baptista, also the creator of the Núcleo, a project she founded together with Nina Kreis. "From love the name of this book happened, from love the Nucleo Marcello Grassmann was born. From love for graphic arts, for Brazilian art, for artist Marcello, his craftmanship, his aesthetics, and, finally, but in first place for Marcello, partner, friend, godfather, designer, engraver, artist, master. A man, who if had read this last sentence, would laugh and say 'Are you writing my epitaph?'" (HKB Translation) --Page 90.
