More Than a Booth.
A Family Tradition.
Nick and Becky Martinez started something special in the 1990s. Nicole carries it forward today.
Built on Passion,
Passed Down with Pride
West Corner Supplies has been part of the Frank & Son Collectible Show community since the early 1990s — back when the show was still finding its footing and the collectibles world felt like the best-kept secret in Southern California.
It started with Nick and Becky Martinez. They had a love for the collectibles community that was hard to contain within four walls, and a practical eye for what collectors actually needed — not just the cards and comics themselves, but the sleeves, binders, bags, boards, and boxes to protect them. Frank & Son gave them a place to serve that need for a community of people who got it.
For over two decades, they built something at Booth #216 that went beyond inventory: a reputation. Repeat customers who'd been coming back for years. Relationships with collectors across Southern California. A name that people trusted. When Frank & Son moved from its original Walnut location to the new City of Industry facility in 2020, West Corner Supplies moved with them — same booth number, new building.
Community First
Built on relationships, not just transactions. Many of our customers have been with us for decades.
Family Values
Started by parents, carried forward by their daughter. Every decision reflects that.
Trusted for Decades
Over 25 years at the same show. We're here because the community keeps coming back.
The Next Chapter
When Nicole Martinez took over, she didn't inherit a business — she inherited a legacy. And she treats it that way.
Today, West Corner Supplies carries that same spirit forward. The faces may have changed, but the care hasn't. Nicole shows up every Wednesday, Saturday, and Sunday with the same commitment to quality, fairness, and community her parents modeled for her.
That's over 25 years of showing up. Of knowing your customers by name. Of being the kind of booth people bring their friends to — and then bring those friends back again.
We're grateful for every customer who's made that possible — and for every new one we get to meet.
— Nicole Martinez & the West Corner Supplies family
