The summer G.A.S. Card Show brings 220 tables back to The Pavilion at John Knox Village in Lee's Summit, Missouri on Saturday and Sunday, June 12 and 13, 2027. June is the sweet spot of the card show calendar in Kansas City — school is out, the baseball season is in full swing, and the summer edition consistently draws the widest cross-section of collectors of any Lee's Summit weekend.
Hours are Saturday, June 12 from 10:00 a.m. to 7:00 p.m., and Sunday, June 13 from 10:00 a.m. to 5:00 p.m.
Admission is $5 daily or $8 for the full weekend at the door, with children 12 and under free.
The Pavilion at John Knox Village is at 520 NW Murray Road in Lee's Summit, with a large free parking lot at the venue.
With school out, this is the most family-friendly of the Lee's Summit weekends, and $8 for two days with free entry for kids makes it easy.
The full G.A.S. tour calendar, dealer table pricing and hotel discount information are published at gas-shows.com, with vendor announcements posted on Facebook ahead of each show.
