The spring edition of the G.A.S. Card Show fills The Pavilion at John Knox Village in Lee's Summit, Missouri with 220 tables on Saturday and Sunday, April 3 and 4, 2027. April lands the show squarely at the opening of baseball season, and Greatest American Sportscard Shows schedules it that way on purpose — the Royals are back, new Topps and Bowman product is on shelves, and the room reflects it.
Hours are Saturday, April 3 from 10:00 a.m. to 7:00 p.m., and Sunday, April 4 from 10:00 a.m. to 5:00 p.m.
Admission is $5 per day or $8 for the weekend, paid at the door.
The Pavilion at John Knox Village is at 520 NW Murray Road in Lee's Summit with a large free on-site lot.
Families get two days of access for $8 with kids free.
The complete G.A.S. tour calendar, dealer table pricing and hotel discount codes are published at gas-shows.com. The promoter posts vendor announcements and last-minute floor updates on Facebook ahead of each show.
