Poetry was the largest component of the original green folder.
Looking back now I see it was heavily weighted to Yeats whom I had just been studying and Ferlinghetti whose "An Eye On the World' has always been a favourite. The Mersey poets from the slim 'Penguin Modern Poets 10' make up much of the rest.
There are three powerful poems by Sassoon and Wordsworth gets two as do Brooke, Cornford, and Synge in 'Other' where they are joined by single entries from Chesterton, Graves, Monro, Wolfe, Masefield, Belloc and Byron, and one written by a schoolfriend for me to submit as homework. My memory is that it cost me sixpence, in the event well-spent!
