I Saw The Letter F in the Gutter

Seen near the site of a street shrine to Henry Kelly on Buena Vista Terrace, in SE Washington DC.

Homage to Charles Demuth's I Saw The Figure 5 in Gold, inspired by William Carlos Williams poem, "The Great Figure":

"Among the rain
and lights
I saw the figure 5
in gold
on a red
fire truck
moving
tense
unheeded
to gong clangs
siren howls
and wheels rumbling
through the dark city"

And, here, I found the letter F, in the gutter, a few sad steps from a murder site...
