O Baú is where we keep our most cherished childhood treasures — but when was the last time we opened it? What secrets might be hidden inside? This book invites us to revisit the toys that shaped our early years and reflect on how, in some ways, they’ve become part of our adult lives too. In this multi-format project, we’re encouraged to let our inner child explore freely — to write, scribble, take notes, and simply have fun along the way.
