The Tri-Star Collectors Show returns to NRG Center for a powerhouse three-day Houston sports card and memorabilia convention from Friday, May 15 through Sunday, May 17, 2026. Produced by Tri-Star Productions — the Houston-based company that has shaped the Texas sports collectibles scene for more than four decades — this show is the flagship Houston card event of the spring and one of the most respected regional conventions in the country, combining a massive dealer floor with one of the strongest autograph guest lineups on any non-National tour stop.
The Tri-Star vendor floor is built around an unmatched selection of sports cards and memorabilia. Baseball card dealers bring vintage T206 tobacco cards, 1950s Topps Mantle and Mays, 1960s and 1970s Topps rookies, 1980s and 1990s Upper Deck and Topps staples, and modern Topps Chrome, Bowman, Stadium Club, and Panini releases with deep Houston Astros, Colt .45s, and Texas Rangers inventory featuring Biggio, Bagwell, Altuve, Alvarez, Berkman, Nolan Ryan, and current World Series era stars. Football card tables stock vintage Topps Houston Oilers Earl Campbell, Warren Moon, and Bum Phillips era cards alongside modern Texans C.J. Stroud, Nico Collins, and Will Anderson Jr. hits plus full NFL coverage. Basketball card vendors feature 1980s Fleer and Star company rookies, 1990s Upper Deck and Topps Chrome, and modern Panini Prizm, Select, Optic, and National Treasures with Houston Rockets Hakeem Olajuwon, Clyde Drexler, Yao Ming, James Harden, and current Rockets rookies. UFC, boxing, MLS Dynamo, Dash, and college football with a strong University of Texas and Texas A&M presence round out the sports lineup. Graded slabs from PSA, BGS, SGC, and CGC are everywhere on the floor. On-site grading submission through PSA and Beckett is typically available at Tri-Star shows, and autograph signings with major past and present sports legends are a defining feature.
The Tri-Star Collectors Show runs Friday, May 15 from 3:00 PM to 8:00 PM, Saturday, May 16 from 9:00 AM to 6:00 PM, and Sunday, May 17 from 9:00 AM to 4:00 PM. General admission runs $10 to $15 per day depending on the day, with three-day passes and VIP early entry options available through tristarproductions.com. Autograph signing tickets are sold separately for each guest and frequently sell out in advance — purchase early. Children 10 and under are typically admitted free with a paying adult.
NRG Center sits at 1 NRG Parkway near the Medical Center and is easily accessible from I-610, I-69, and the MetroRail Red Line. Ample on-site paid parking is available, and dozens of restaurants and hotels are within a five-minute drive.
This show is essential for Houston sports collectors building Astros, Texans, Rockets, Dynamo, UT, and A&M collections, dedicated autograph hunters, graded card investors, and families seeking a major-league hobby weekend.
