Vest-Pocket Adding Machine Print Ad

This old ad for a “Vest-Pocket Adding Machine” pulls off something rare — it gives the product a voice! The calculator literally speaks to the reader in first-person, making the copy fun, human, and impossible to skim.

Marketing Analysis

By turning the machine into the narrator, the ad creates a bond with the buyer. Instead of describing features, it brags about them. It’s personality-driven copy decades before “brand voice” became a thing.

Why It Works

• Personifies the product, making it relatable and memorable
• Rapid-fire short sentences keep attention high
• Turns dry features into benefits with charm and confidence
• Directs action with conversational commands (“Get acquainted with me; don’t delay”)

Examples

• Mailchimp’s quirky tone makes email software approachable
• Old Spice ads with “The Man Your Man Could Smell Like” humanize a brand
• Duolingo’s owl mascot uses personality to drive engagement on social media
