A retro-inspired podcast poster for "The Undercurrents," built around a bold studio microphone angled against a sunburst of orange, yellow, and purple stripes. Layered teal waves roll across the lower half, echoing the show's name and giving the piece a sense of motion beneath a still, waiting mic. The palette and geometric shapes pull from vintage travel-poster design, but the subject - sound, not scenery, turns that nostalgic style into something more current: an invitation to listen, dressed up like an old broadcast announcement.
