A painting by street artist Banksy with an environmental message and an estimate of up to 5 million pounds ($6.3 million) is going up for auction, with some of the proceeds helping victims of the Los Angeles wildfires.

A rare work by Banksy, owned by Blink-182’s co-founder Mark Hoppus, heads to Sotheby's with a $3.8 million estimate.

Expected to sell for up to $6.3 million, Hoppus says proceeds of the sale will go towards charities aiding those affected by the Los Angeles wildfires.
