Greatest American Sportscard Shows returns to Overland Park on Saturday, August 29, 2026 with a free-admission, one-day show at American Legion Post 370. G.A.S. is the most prolific promoter in the Kansas City market, and the Overland Park room is their neighborhood show — smaller and friendlier than the big John Knox Village weekends, but with more than fifty tables packed into a single hall and a reputation for aggressive pricing.
Hours are Saturday only, 10:00 a.m. to 7:00 p.m.
Admission is free for everyone — no tickets, no wristbands, no VIP tier, and no charge for children.
American Legion Post 370 is located at 7500 W 75th Street in Overland Park, a short hop off Metcalf Avenue. Parking is free in the Post lot and on adjacent streets, and the hall is single-level with easy access.
Come with cash — free-admission shows run on it, and most vendors will shave ten to twenty percent off a marked price for a cash bundle.
Full tour dates, dealer table pricing and hotel discounts are published at gas-shows.com, and the promoter posts floor announcements and last-minute changes to their Facebook page in the week before each show.
