At the Semana Negra festival of literature in Gijon, northern Spain, members of the public rush forward to claim copies of this year's Semana Negra book.
Each year, a dozen or so writers and artists are asked to contribute essays, drawings and comic strips on a given theme; this year's was Picasso's Guernica.
Production of the book is paid for by sponsorship, so all copies are given away free, but distribution is on a first-come-first-served basis - hence the urgency.
Button was intermittently attacking dragonflies - though in this case, I think he may have been fleeing Dr. F. I don't know why, I'm the one who trod on him.
