The Museum of Lost and Found Potential is a pop-up museum “showing the hopes and dreams lost to neglected mental health and suicide across the world”. It is open free to the public in London for five days in October, and then will tour the world.
The museum was launched on World Mental Health Day (10 October), with the London cast of Dear Evan Hansen performing the song “You Will Be Found”. They were involved because “The Tony Award-winning musical explores teenage mental health and suicide”.
There is a press release from the museum here, from which the above quotes were taken, and they also shared the photo below of the cast (photographer unknown).
