Input: original question: Which poem character appears in [A Supermarket in California]?
answer: federico garc√≠a lorca, walt whitman
answer type: Poem character.
auxiliary information: "A Supermarket in California" is a poem by American poet Allen Ginsberg first published in Howl and Other Poems in 1956. In the poem, the narrator imagines visiting a supermarket in California where he finds Federico Garc√≠a Lorca and Walt Whitman shopping. Whitman, who is also discussed in "Howl", is a character common in Ginsberg's poems, and is often referred to as Ginsberg's poetic model. "A Supermarket in California", written in Berkeley and published in 1956, was intended to be a tribute to Whitman in the centennial year of the first edition of Leaves of Grass. For its critique of mainstream American culture, the poem is considered to be one of the major works of the Beat Generation, which included other authors of the era such as Jack Kerouac, William Seward Burroughs, and Lawrence Ferlinghetti. Ginsberg achieved critical success in 1956 with the publication of Howl and Other Poems, with "Howl" being the most popular of the works in the collection. Like "Howl", "A Supermarket in California" was a critique of postwar America, yet in the poem the narrator focuses more on consumerist aspects of society by contrasting his generation with Whitman's.
