Our main man Carl really loved Chicago. He titled his first collection of poems Chicago Poems, and filled that baby full of poems about Chicago (including our poem du jour, "Chicago"). Sandburg is probably most well-known for his chronicling of the windy city. You can check out his first book of poems here and note just how many of them are about city life.
And in case you were wondering, Sandburg's love for Chicago was very-much requited. The city is filled with Sandburg nostalgia from this awesome mural to his former home.
