Buick Authorized Service Porcelain Enamel Sign (12in)

Buick Authorized Service—A Legacy of Performance & Luxury

For over a century, Buick has been a leader in automotive engineering, style, and reliability. From its early days pioneering Valve-In-Head engines to its reputation as a premier American luxury brand, Buick has remained a trusted name in performance and innovation. Signs like this were proudly displayed in authorized Buick service centers, dealerships, and repair shops, letting customers know they were getting factory-approved parts and expert care. This vintage-style 12” porcelain sign is a tribute to Buick’s rich history in American automotive excellence, featuring bold branding, classic typography, and a nostalgic dealership-inspired design. A must-have for collectors of vintage Buick memorabilia, classic automotive signage, and American car history.

Remember when things were built to last? When craftsmanship mattered?

We do too. That’s why we don’t cut corners. This Buick Authorized Service 12” Porcelain Sign is built exactly like the originals—real kiln-fired porcelain enamel, layered onto ¼-inch heavy-gauge steel for a finish that lasts a lifetime.

Built Like the Originals—Because It Is.

After 15 years as an auctioneer and lifelong collector, I saw firsthand how true craftsmanship was disappearing. Today’s market is flooded with flimsy aluminum replicas and cheap stickers. We bring back the weight, feel, and durability of true vintage porcelain signs, with hand-punched mounting holes, thick steel, and a rich, baked-on finish.

Key Features:

✔ 12” diameter – Classic size for garages, dealerships, and collections
✔ ¼” heavy gauge steel – Thick, durable, and built to last
✔ Hand-rolled edge – Just like the originals, for an authentic feel
✔ Kiln-fired porcelain enamel – Weatherproof and fade-resistant
✔ Hand-punched mounting holes – No pre-drilled factory shortcuts
✔ Weatherproof for indoor or outdoor display

Satisfaction Guaranteed.

We’re collectors too, and we know how it feels to be disappointed with a purchase. That’s why we stand behind every sign with a no-questions-asked return policy—plus, we cover shipping.
