Design a premium "Screenprint Editorial City Poster" themed "Summer in Guangzhou". It features retro screen-printing texture, modern editorial layout, urban collage and graphic expression, giving a design-annual publishing and collectible feel. The background is a minimal warm beige paper ground with large whitespace, restrained layout with breathing room.
