Shell Oil Certified Compound Advertising Thermometer Sign — Minneapolis, 1950s–60s

A rare and regionally specific piece of petroliana history — this original Shell Oil advertising thermometer was issued for the Minneapolis office in the 1950s to early 1960s to promote Shell's Certified Compound, heating oils.. Regional promotional pieces like this are far less common than national advertising items, making this a standout find for serious Shell or petroliana collectors.

At 14" x 4.5", it's a slim, classic thermometer format that would have hung in service stations and garages across the Minneapolis area during the golden age of American petroleum advertising.

• Promotes Shell Certified Compound (heating oils)

Regional petroliana pieces this specific don't come up often — a great addition for the focused Shell collector.
