Modern marketing doesn’t always require million-dollar budgets or complex licenses. Thanks to the public domain, companies can take advantage of iconic characters, illustrations, and photographs without infringing copyright. From Sherlock Holmes to classic works of art, these creations offer an unlimited source of creativity and possibilities for advertising campaigns.
In this article, we’ll explore what the public domain really means, how to apply it in marketing, and concrete examples of characters and images you can freely use to connect with your audience.
What is the public domain and why is it important for marketing?
The public domain refers to works that are no longer protected by copyright or never were. This means anyone can use, modify, and share them without paying licenses or requesting permission. Most of these works include creations whose rights have expired, government materials, or classic literary characters.
For marketing professionals, the public domain represents a huge strategic advantage. It allows brands to take historical characters, illustrations, and photographs, reinterpret them, and give them new meaning within modern campaigns. It also makes it possible to connect with audiences through well-known cultural references, generating familiarity and trust without major investment.
⚠️ Important: Not all versions of a character are free to use. For example, the original 1928 design of Mickey Mouse is now in the public domain, but modern Disney versions are still protected by copyright. Knowing how to distinguish between these versions is key to using the public domain correctly in marketing.
Iconic public-domain characters that inspire creativity
Throughout history, many characters have entered the public domain, becoming ideal resources for brands seeking originality and emotional connection.
Classic literary characters
- Classic literary characters are an incredible resource for marketing because they’re deeply rooted in popular culture. Their stories and personalities are instantly recognizable, allowing campaigns to connect quickly with audiences. In addition, these characters carry centuries of history, adding prestige and depth to any communication.
- Sherlock Holmes: more than a detective, he’s a symbol of wit, analysis, and problem-solving. His image can be used in educational campaigns, innovation initiatives, or products that require intelligence and precision.
- Dracula and Frankenstein: gothic horror classics are perfect for creating mystery, curiosity, or visual impact in Halloween campaigns, entertainment, or even disruptive products.
- Children’s tales: stories like Alice in Wonderland, The Wizard of Oz, or early versions of Peter Pan offer complete worlds that can be reinterpreted for social media, ads, and visual content. The nostalgia these characters evoke helps connect with multiple generations, creating instant emotional touchpoints and familiarity.
In marketing, these figures don’t just convey values or emotions—they also open the door to narrative campaigns where the story itself becomes a branding asset, allowing original tales to be reimagined with a modern, creative twist.

Historical animation characters
Early animation also offers unique opportunities for marketing campaigns. Many iconic characters from the beginnings of cinema and animation have entered the public domain, allowing brands to use them at no cost and with full creative freedom.
The 1928 version of Mickey Mouse, as he first appeared in Steamboat Willie, is now in the public domain. This opens up a huge range of possibilities for retro, vintage, or nostalgic campaigns—reimagined through illustrations, animated ads, merchandising, or social media posts.
His classic, simple, and recognizable style gives campaigns an iconic and trustworthy feel, evoking childhood memories and pop culture. Reinterpreting vintage Mickey can also help differentiate your brand, showcasing creativity while playing with history and collective memory. By combining literary characters with historical animation, marketers can build unique campaigns with strong storytelling, emotional connection, and memorable aesthetics—without spending a single euro on licenses.
Works of art and historical images: an unlimited source for marketing
The public domain isn’t limited to literary or animated characters. Classic artworks and historical photographs are another valuable resource:
- Paintings by Van Gogh, Monet, Leonardo da Vinci, or Rembrandt can be adapted for campaigns seeking sophistication, aesthetics, and prestige.
- Vintage photographs and historical maps, available in digital libraries like the Library of Congress or Europeana, enrich content and corporate storytelling.
These works make it possible to create original, educational, or narrative campaigns without paying licenses, adding extra value by connecting with history, culture, and universal creativity.
⚠️ Some modern reinterpretations are still protected by copyright, so it’s always essential to verify the source and age of a work before using it.
How to apply the public domain in your marketing campaigns
Strategic use of the public domain enables distinctive, low-cost campaigns.
- Social media: create original visual content using classic illustrations or reinterpreted literary characters to boost engagement and communicate creativity and approachability.
- Branding: reimagining classic characters or incorporating historical art into products, packaging, or merchandising adds a distinctive brand touch.
- Storytelling: combining well-known works with modern messages builds emotional connections without major investment.
- Educational content: newsletters, ebooks, or blog posts enhanced with public-domain images stand out for their visual and educational value.
