Humorous Political Cartoon exhibition posters

I'm seeking a creative designer to produce 5 educational posters for college students and older, all centered on the history and meaning of political cartoons. Each poster should cover a different topic and convey an engaging and humorous tone. The thing will be presented as an exhibition forr all audiences even though it is supposed to appeal to students it has to be inclusive. Most important is the educational part: so the core and wit of message.

The specific topics should include:
- The historical evolution of political cartoons
- Key figures and artists in political cartooning
- The impact of political cartoons on public opinion

The ideal freelancer would have:
- A strong understanding of political history and cartooning
- The ability to convey complex ideas in an engaging, humorous way
- Ability to write in a storytelling way
- A portfolio demonstrating similar past work.
