New York’s Voltz Clarke Gallery is mounting “Variations,” an exhibition of linear paintings by artist Joshua Avery Webster, on view in the solarium throughout the Palm Beach season. Additionally, a work entitled Hammon Avenue by Voltz Clarke artist Bradley Sabin adorns the Colony mezzanine, surrounding a scalloped-back love seat upholstered in an exuberant print featuring a swirl of 150 sculptural magnolia blossoms.
