From the convention’s official homepage:

Planet Comicon is Kansas City’s largest comic book and pop culture convention.  The 2013 show promises to be our largest yet.

Join us on April 6th and 7th at our new venue, the Kansas City Convention Center, to find a vast assortment of creators, media guests, vendors, and cosplayers.  With nearly twice the space as in previous years, we’re pulling out all the stops to make certain that this will be something you’ll be talking about for years to come.
