Founded by Marc Nathan, owner of Cards, Comics, and Collectibles of Reistertown, Maryland, the show was originally a one-day show held at the Sheraton Hotel in the Chartley Shopping Center, located in the Baltimore suburb of Towson, Maryland.

 

The show continued to grow in size, and in 2002, it show moved to the Baltimore Convention Center in downtown Baltimore, across from Camden Yards and down the street from Geppi's Entertainment Museum, and was extended to a two-day show. In 2014, responding to demand from attendees and exhibitors, the show moved to a three-day event, from September 5 to 7.
