Which 1950s McDonald's restaurant design introduced the famous Speedee service sign?

The Golden Arches restaurant design introduced the famous Speedee service sign.

Architect Stanley Meston created the distinctive design for McDonald's restaurants in the 1950s. Its most recognizable features were two tall yellow arches rising from the sides of the building, a sloped roof, and prominent roadside visibility. The arches helped motorists identify the restaurant before the later standalone logo became dominant.

The Speedee service sign connected the building to McDonald's quick-service promise. Speedee was the earlier hamburger mascot and a visual shorthand for fast preparation, while the arches communicated the restaurant's physical identity from a distance.

The building design and the modern logo are related but not identical. The original arches were three-dimensional architectural structures; Jim Schindler later combined their visual forms into the flat M-shaped emblem used in corporate branding.
