設計工作室開放日海報（手作拼貼風）

prompt

Create a portrait 2:3 poster announcing an open-studio day for {agency_name}, a creative agency. Style: analog paper collage — torn magazine scraps, halftone photo cutouts of hands, scissors and color swatches, masking-tape edges, and bold cut-out letterforms arranged at slightly rotated angles. Layer the headline 'OPEN STUDIO' as oversized ransom-note typography across the upper two-thirds. Below, place a cream paper strip listing {event_date} and {studio_address} in typewriter font, and a smaller torn label teasing {activity_highlights}. Background: warm kraft-paper texture with one bold spot-color accent. Keep the composition energetic but leave breathing room around the date strip. High-resolution print output.
