This Andy Warhol’s worth a whole lotta soup cans.

A self-portrait the artist sold on an installment plan for $1,600 in 1963 is expected to sell for at least $30 million at auction next month. The four-panel “Self-Portrait,” in which Warhol is pictured in a trench coat and sunglasses, will be sold by Christie’s on behalf of the family of collector Florence Barron.
