There was a painting of Keanu that was for auction at the Global Initiative Charity.
Many thanks to global.charity.initiative for sharing a photo of the painting of Keanu on IG story here.
Many thanks to giulialupettireal for sharing a photo and two clips of the painting on IG story here, here and here.
Note: Keanu did not show up at the benefit according to a comment by swedish_bella2 on instagram (half way down the comment thread). Instead of going to the benefit, it appears that Keanu decided to go shopping at Whole Foods instead according to @__tomasitooo__ who tweeted that she saw him there.
