Per the HQ Blog:
World Postcard Day 2025 is coming up, and we’re excited to announce a souvenir to honor the occasion! Celebrate with us by attending an Event and posting an Attended log on any Event from September 28 to October 4, 2025. All Events, including Community Celebration Events and Block parties, count for the souvenir!
Let's gather at the posted coordinates in Redbud Park located in the NOTO district at 10:30am. We will plan on taking our group photo at 10:45am in front of the Greetings from Kansas mural.
