Every July, over 130,000 collectors and fans gather in San Diego for the ultimate pop culture and collectibles convention. From its 1970 origins as a small comic book show, the convention has evolved into a major event where Hollywood studios promote their latest releases. Throughout its evolution, it maintains its status as the most important event on the calendar – not just in comics, but also in toys and the broader collectibles space.

Every second a sports or trading card is sold on Whatnot. And every summer, the Whatnot community and the hobby at large gather at the largest sports card and memorabilia convention in the U.S: The National Sports Collectors Convention. This year, we’re headed to Cleveland, Ohio from July 24-28.
