The Mimi Fishman Foundation has launched an online auction featuring rare concert posters signed by the members of the band Phish. The collection includes artwork from the 2026 Phish Summer tour and the band's 2026 Spring Sphere performances.
Why it matters
The auction serves as a fundraising initiative to support various charitable organizations backed by the Mimi Fishman Foundation and the WaterWheel Foundation. These funds provide critical backing for diverse causes championed by the fan-led groups.
