Cross-Product Creative Challenge #11: PSA Posters from an Alternate Timeline
Welcome to a new Cross-Product Creative Challenge! Thanks to everyone who participated in the temporal mash-up. This time, we're messing with history again, this time with a civic or propaganda poster from an impossible timeline.
The Challenge:
Design a civic poster—propaganda, safety warnings, or recruitment ads—for a world that runs by different rules. Maybe it's a world where air is a subscription service, or where silence is the local currency. Maybe it's
- “Join the Venus Terraforming Corps – 1939”
- “Steam Rail to the Moon – Great Western Aether Lines”
- “Vote for the AI Party – 1968”
Go crazy. Start in Firefly or Boards or Express or Photoshop, but use at least two different tools to get to your final product.
Guidelines:
- A prompt is not enough. Layer your assets and refine your composition. Treat Firefly as a collaborator, not a shortcut. Use prompts to generate characters. Try out partner models.
- Think like a director. What’s the story here? Who are the characters? What's happening in the scene?
- It’s a Cross-Product Challenge! Don't do it all in Firefly. Use Photoshop, Illustrator, Substance, Adobe Express, Fresco—whatever tools will help you build the scene.
- Share your process. Tell us how you created it. What tools did you use? How did you refine your idea? What choices did you make?
My example is a PSA from the U.S. government Department of Gravity.

The base is a typical 1950s American family scene generated with Nano Banana. The tie-downs and safety harnesses are Generative Fill using Firefly 3, adjusted and composited in Photoshop. The departmental logo was generated in Adobe Illustrator using the Gemini partner model. Because this is a thinly veiled threat, I generated a hapless golfer who didn't pay his license fee. Text added in Photoshop.
