"There’s no question Hancock’s signature is the biggest, and by a wide margin. By my measurements, Hancock’s signature comes in at 1.3 inches tall and 4.7 inches wide. This makes the box needed to enclose the signature 6.1 square inches. Compare that with Sam Adams’ signature, which takes up a mere 0.6 square inches of surface area."
