Thought Bubble (also known as the Yorkshire Comic Art Festival) is an annual comics art festival and comic book convention held in Yorkshire. Established in 2007, Thought Bubble has been credited as being the UK's largest comics convention. The not-for-profit festival's chosen charity is Barnardo's. Thought Bubble takes place for a week in November each year (in conjunction with the Leeds International Film Festival), taking place all over Yorkshire, and culminates in a two-day convention in Harrogate. A dance party is usually held on the Saturday night before the festival's final day.
