History Lesson

I am four in this photograph, standing
on a wide strip of Mississippi beach,
my hands on the flowered hips

of a bright bikini. My toes dig in,
curl around wet sand. The sun cuts
the rippling Gulf in flashes with each

tidal rush. Minnows dart at my feet
glinting like switchblades. I am alone
except for my grandmother, other side

of the camera, telling me how to pose.
It is 1970, two years after they opened
the rest of this beach to us,

forty years since the photograph
where she stood on a narrow plot
of sand marked colored, smiling,

her hands on the flowered hips
of a cotton meal-sack dress.
