I’ve pored over grainy sepia pictures of long-dead relatives in babushkas; black-and-white snapshots of distant cousins in crisp white linen suits, soldiers in uniform, ladies with beehive hairdos; Polaroids of bell-bottomed teenagers and long-haired hippies, and not once have I been able to detect even the slightest trace of August’s face in their faces.
What does "polaroids of bell-bottomed" and "August’s face" mean?
