Perfect Pairing Pop Up Party – A GCA × USPS Event!
We’re thrilled to announce an opportunity to participate in a new Greeting Card Association event – the Perfect Pairing Pop Up Party – a collaboration between the GCA and US Postal Service on April 18, 2026 at Track 15 in Providence, RI. from 11 AM – 4 PM. Join us as we celebrate the unveiling of a new USPS stamp with a pop-up retail market with 20 vendor spots for GCA members to sell cards, stationery, stickers and more. This Perfect Pairing Pop Up Party combines a USPS First Day of Issue ceremony with a direct-to-consumer pop up market, creating a special opportunity to connect with both stamp collectors and stationery fans.
This event will be open to the public. We’re expecting 250 attendees (hopefully more) throughout the day comprised of stamp enthusiasts attending the First Day of Issue ceremony, local families who regularly attend weekend events at Track 15, students from the nearby Rhode Island School of Design (RISD), Brown and Providence College campuses and friends and families of the GCA.
The event is a direct extension of our ongoing Perfect Pairing project, which encourages GCA publishers to showcase their favorite card and USPS stamp combinations on social media. In addition to the newly issued stamp, the USPS will also have four other stamps available for purchase to inspire even more Perfect Pairings: Love, Sunflowers, Dahlias, and Baby Wild Animals. A USPS retail station will be set up at the event for all stamp purchases.
Vendor registration for the event is open! Only 20 vendor spots are available and will be first-come, first-served. Click here for registration form.
