The Petroliana Glossary

Auctions, forums, and dealers all lean on a shared vocabulary. Search the terms every collector should know — from banjo signs to fantasy pieces.

Attic / Barn Find
An item discovered in long-term storage, often unrestored and freshly to market.
Banjo Sign
A round-topped, narrow-necked porcelain sign shape, famously used by Texaco.
Clock Face Pump
A pump with a large round dial indicating gallons dispensed.
Curb Sign
A free-standing, often double-sided sign placed at the roadside or curb.
Die-Cut
A sign cut to the outline of a logo or figure rather than a plain rectangle — highly desirable.
Fantasy Piece
A sign or globe made in a design that never actually existed historically — a trap for new buyers.
Field
The main background area of a sign, as opposed to its border or graphic.
Figural
A sign or item shaped like a recognizable object or character, such as Sinclair’s Dino.
Flange Sign
A double-sided sign with an L-shaped bracket for mounting perpendicular to a wall.
Ghost
A faint image left where paint or graphics have worn or faded away.
Gill / Glass Body
A globe whose body is glass (Gill being a noted maker), as opposed to a metal or plastic body.
Grade
A shorthand condition score, commonly on a 1–10 scale, used to price a piece.
Grommet
The metal ring set into a mounting hole of a porcelain sign to prevent chipping.
Lens
The printed or etched glass insert that carries the brand graphic on a pump globe.
Lubester
A tall dispensing cabinet used to sell bulk motor oil at the service station.
Mint / Near-Mint
Top condition grade — full gloss and crisp graphics with little to no damage.
NOS
“New Old Stock” — an original period item never used or installed, still in as-made condition.
Oil Can (Quart)
The quart-sized motor-oil container; full, unopened cans with sharp graphics are sought after.
One-Piece Globe
An early globe molded as a single piece of glass — scarcer and generally more valuable than lens-in-body types.
Patina
The aged surface character of an original item; honest patina is prized, faked patina is a red flag.
Pecten
The scallop-shell emblem of the Shell brand.
Petroliana
The umbrella collecting field for gas- and oil-company advertising and equipment.
Porcelain Enamel
Powdered glass fused to steel in a kiln, layer by layer, giving signs their glossy, durable color.
Provenance
The documented ownership history of a piece, which can add value and confidence.
Pump Globe
The illuminated glass globe crowning a gas pump, made of a body and one or two glass lenses.
Repop / Repro
A modern reproduction of a vintage design, legitimate as decor but not collectible as an original.
Rocker / Restored
A piece that has been repainted or rebuilt; advanced collectors value original surfaces more highly.
Sign Shop Mark
The maker’s stamp along a sign’s edge, often useful for dating and authentication.
Single / Double-Sided
Whether a sign is printed on one face or both; double-sided flange and curb signs are common.
Station Sign
The large primary identification sign that hung at a service station.
Touch-Up / Touch-Out
Small areas of added paint used to hide chips or losses on a sign.
Visible Pump
An early gas pump with a glass cylinder up top so drivers could see the fuel before it was dispensed.
