Vintage advertising signs—gas and oil, soda brands, automotive, farm equipment, railroads, and general store décor—are among the most reproduced categories in the collectibles world. Because authentic porcelain and tin signs can bring high prices, the market is saturated with replicas, artificially aged pieces, and intentionally misleading fakes that can easily fool beginners.
DJR Expert Guide Series, Vol. 668 gives you a complete, beginner-friendly, non-destructive workflow for evaluating vintage signs. Using simple visual techniques—no scraping, no chemical tests, and no cleaning—you’ll learn the same observational methods used by professional sign authenticators.
Inside this guide, you’ll learn how to:
Identify authentic materials such as porcelain enamel, painted steel, tin lithograph, and early wood signs
Distinguish genuine enamel firing from powder coating, printing, and modern substitutes
Evaluate construction quality, weight, and thickness to detect thin or flexible fakes
Analyze rust patterns, aging behavior, and natural versus artificial wear
Examine mounting holes for correct enamel chipping, oxidation, and period hardware clues
Spot incorrect fonts, logo styles, character details, and misaligned graphics
Recognize color palettes consistent with period manufacturing
Confirm correct sizing, shape, and format for well-documented sign types
Detect artificial distressing methods such as sanding, spray rust, and chemical aging
Inspect the backside of a sign for the most revealing authenticity clues
