The Green Collection 1 Samuel Papyrus and Mummy Cartonnage. Incidentally, per Scott Carroll's quoted comment, this is not "the earliest text of 1 Samuel in the world." Among the Dead Sea Scrolls, 4QSamuelb (4Q52) is dated by Cross to c. 250 BCE and 4QSamuela (4Q51) and 4QSamuelc (4Q53) to the first century BCE. This Greek papyrus seems to be from the early third century CE (or later? - See the second post below). That is still very early. It may be the earliest surviving papyrus copy or Greek copy or both. I don't know.
