Tied up at the sun-drenched dock of Lewis Cove in Hyannis, the wooden fishing vessel Sea Hawk (registration 46344) rides low in the blue harbor water, her yellow-trimmed hull gleaming against the busy working waterfront behind her — a scene that captures Cape Cod's mid-century fishing culture at its most authentic. The "Pat & Don" sign on the dock's edge hints at the family enterprises that lined these piers, where generations made their living dragging nets through Nantucket Sound. Produced in Plasticchrome color by Colourpicture Publishers of Boston for The Slate Co. of Hyannis, this chrome-era card is a vivid snapshot of a Hyannis Harbor that predates the Kennedy-era tourist boom that would soon transform the Cape's identity forever.
