Photo: Yoko Ono: My Mommy Is Beautiful (2004).
Stretched and primed linen canvases, paper, pens, tape, glue, table, chair, artist's holograph instructions. Visitors were invited to write a thought or memory about their mothers, or bring a photograph, and attach it to the canvases.
"Very quickly, the canvases became completely covered in memories and messages, which soon covered the walls as well," Ms. Ono writes.
She invites Boing Boing readers to engage in an online version of this project here: My Mommy is Beautiful / 2010.
