Creating Advertising Designs with AI: Using the “In the Style Of” Method

Quote Now!

Modern artificial intelligence tools allow designers to create professional advertising visuals in minutes. One of the most effective techniques is generating images “in the style of” well-known posters, illustration styles, or historical design movements.

This approach makes it possible to quickly create strong visuals for:

  • posters
  • car magnets
  • A-frame signs
  • banners
  • storefront graphics
  • promotional posters

Instead of starting from a blank page, we start from a proven visual style that already works.

Example: Using a Famous Poster Style

One of the most recognizable posters in history is the famous “I Want You for U.S. Army” recruitment poster.

It works extremely well because:

  • the character points directly at the viewer
  • the composition is very simple and powerful
  • the typography is clear and bold
  • the design instantly grabs attention

Original poster style

     

AI Generated Result Using This Style

Using the same visual composition and poster logic, we can generate a modern advertising image.

Example result

       

Notice what remains similar:

  • character pointing at the viewer
  • vintage poster texture
  • limited color palette
  • strong typography

But the image itself is completely new and tailored for a modern business.

How the Process Works

The process is simple and efficient.

Step 1 – Choose a Style

First we select a visual style that fits the message.

Examples include:

  • vintage propaganda posters
  • retro advertising
  • comic book style
  • Bauhaus / modernist posters
  • Soviet constructivist posters
  • industrial vintage design

We use the style as inspiration, not copying the original artwork.

     

Step 2 – Create the Prompt

Next we write a description for the AI system.

Example prompt:

  • vintage recruitment poster style similar to early 20th century propaganda posters,
  • cute samurai cat in red armor pointing forward at the viewer,
  • bold typography,
  • aged paper texture,
  • limited color palette,
  • high contrast,
  • vintage poster layout,
  • text: SIGN UP NOW! SIGNS 25% CHEAPER
  • website: QuarterCheaperSigns.caThe AI analyzes the description and generates a new original illustration.

Step 3 – Generate Several Versions

In practice:

  • a good result often appears after 1–2 attempts
  • an excellent result almost always appears by the 4th or 5th attempt

This is a normal workflow when using AI.

Generating several variations takes only a few minutes.

     

Why This Method Works So Well

Human brains instantly recognize strong visual compositions.

Classic posters were designed by experts to:

  • capture attention quickly
  • communicate the message instantly
  • be readable from far away
  • remain memorable

When we apply these proven design principles using AI, we can produce very effective advertising visuals extremely quickly.

Example #2 – Soviet Constructivist Poster Style

Soviet posters from the 1920s and 1930s are famous for their bold visual language.

Characteristics include:

  • strong geometric composition
  • limited colors (often red, black, beige)
  • very bold typography
  • high contrast graphics

Historical style reference

     

AI generated advertising interpretation

This style works extremely well for:

  • posters
  • banners
  • A-frame signs
  • window graphics

Because it is very visible from a distance.

     

Why AI Design Is Perfect for Small Businesses

Traditional design process:

  • concept development
  • sketching
  • illustration
  • layout and typography

This can take hours or even days.

With AI assistance:

a strong visual concept can appear in 5–15 minutes.

After that, the design only needs:

  • text adjustment
  • layout adaptation
  • print preparation

Where These Designs Work Best

This method is especially effective for:

A-Frame Signs

Drivers must understand the message in 1–2 seconds.

Car Magnets

The design must be simple and bold.

Banners

High contrast and strong composition are critical.

Storefront Posters

They need to attract attention from across the street.

         

Limited Colors = Better Advertising

Most successful posters use a limited color palette.

Typically:

  • 3–5 colors
  • strong contrast
  • large typography

This makes designs:

  • easier to read
  • more visually powerful
  • cheaper to print
