Read the sign.
Then read the object.
Identify porcelain, tin, neon, wood, glass, paper, and plastic signs through construction, maker marks, mounting, wear, provenance, and exact format—not the logo alone.
Material changes the entire investigation.
A porcelain pump plate, lithographed tin sign, reverse-painted glass panel, cardboard counter display, and restored neon can share a brand but require different authentication and preservation methods.
Porcelain enamel
Gloss, chips, layered color, steel, holes, edges, and maker marks.
Painted tin
Lithography, embossing, bends, oxidation, backs, and printed detail.
Neon
Original cans, replacement tubing, transformers, wiring, and restoration.
Wood
Hand lettering, carving, layers, construction, mounting, and local history.
Photograph before cleaning.

The logo is the easiest part to copy.
Strong authentication combines a documented design with period-appropriate dimensions, material, manufacturing, edge treatment, mounting, back, maker information, and natural use. Artificial aging on the front cannot compensate for contradictory evidence elsewhere.
“Old,” “vintage style,” “reproduction,” “licensed,” “fantasy,” and “original” are not interchangeable descriptions.
Use the authenticity guide
Match the format before the price.
A small reproduction, an original pump plate, a restored pole-sign face, and a newly enameled licensed sign can carry similar artwork but belong to completely different markets.
