The Cardboard Collectors Show returns to the Fort Bend County Fairgrounds in Rosenberg for a late-summer weekend on Saturday, August 22 and Sunday, August 23, 2026. A recurring favorite on the southwest side of the Houston metro, this vendor-focused show fills Building C at the fairgrounds with tables of cards and collectibles, giving collectors in Rosenberg, Richmond, Sugar Land, Katy, and greater Houston a two-day hobby destination without the drive downtown.
Admission at Cardboard Collectors Shows is collector-friendly, typically free or a few dollars at the door, with kids welcome; confirm current door details on the event page.
The Fort Bend County Fairgrounds sit at 4310 Highway 36 South in Rosenberg, just off the US-59/I-69 corridor about 35 minutes southwest of downtown Houston. Fairgrounds venues are built for events like this: parking is plentiful, free, and steps from the building — a real advantage over hotel and downtown shows — and Building C's open exhibition layout keeps sight lines clear and aisles wide.
For exact hours, table counts, and updates on this date and the series' November and December returns to the fairgrounds, see the event listing on Card Show Dex at cardshowdex.com/houston.
