A man walks down the steps of the National Libray of Spain, as a crossword made out of macrame is seen hanging on its fence, on World Book Day, in Madrid, April 23, 2015. World Book Day is annually celebrated on April 23, to pay tribute to books and authors, and to encourage reading. The date is the anniversary of the deaths of Spanish author Miguel de Cervantes, British playwright and poet William Shakespeare and writer Inca Garcilaso de la Vega, who was born in Peru. The words in the puzzle read, "book" (vertical on L) and "comma". REUTERS/Andrea Comas
