Gallery Opening Night Poster

A discreet gallery opening-night poster, vertical A1, advertising a solo painting show. Layout follows a strict three-column Swiss grid. Left and middle columns are pure off-white space. Right column carries a single tall vertical close-up of a thick impasto brushstroke in oxblood and warm white paint, photographed straight-on with raking studio light so the ridges of pigment cast tiny shadows, edges bleeding to the page edge. Top-left of the poster: tiny tracked-out caps "OPENING TUESDAY". Center-left, set midway down: a large left-aligned thin transitional serif reading "Slow Weather"; immediately under it, a single italic line "new paintings by Iona Verriest". Bottom-left block in two tidy lines: "6 to 9 PM / wine and conversation" and "Halberd Gallery / 14 Cleaver Lane / through July". Color: 90% warm off-white paper, oxblood paint, charcoal type. Texture: barely-there uncoated paper grain. Mood: quiet, confident, art-world insider tone.
