Fans united to celebrate San Diego Comic-Con, which took place at the San Diego Convention Center from July 25–28. Over the course of four days, thousands of guests attended the convention, which featured panels, cosplaying, and opportunities to meet creators and costumed characters alike. Children’s publishers partook in the festivities, and we’ve rounded up the highlights here.
