Which McDonald's visual symbol was inspired by the restaurant buildings' yellow side arches?

The Golden Arches symbol was inspired by the yellow side arches on early McDonald's restaurant buildings.

Architect Stanley Clark Meston designed the distinctive building for Richard and Maurice McDonald's restaurant in San Bernardino, California. Its two tall yellow arches were visible from the road and helped make the small drive-in recognizable. The arches were architectural features before they became a corporate logo.

McDonald's later transformed the two separate structures into the familiar stylized M. The arches became especially powerful as roadside branding because motorists could identify them from a distance. Their color and simple shape also made them easy to reproduce on signs, packaging, uniforms, and advertising.

A common mix-up is assuming the symbol was invented as a letter M from the beginning. Historically, it developed from actual building design. The logo's later meaning is linked to McDonald's, but its origin lies in the restaurant's architecture and roadside visibility.
