Rowe advertised in newspapers of wide circulation and otherwise made known that she would pay $5,000 for a complete set consisting of ten volumes of certain rare books. Ford, not knowing of the offer, gave Rowe all but one of the set of rare books as a Christmas present. Ford later learned of the offer, obtained the one remaining book, tendered it to Rowe, and demanded the $5,000. Rowe refused to pay. Is Ford entitled to the $5,000?
