Benjamin Schwenk entertains a crowd in his custom-made costume on the last day of the Comic-Con International 2011 convention held in San Diego on Sunday, July 24, 2011. The four-day convention, which started in 1970 to showcase comic books, science fiction, fantasy, film and television, has ballooned into the largest convention in America, attracting well over 100,000 (frequently costumed) attendees each year.
