In McDonald's branding history, which 1950s design feature inspired the Golden Arches logo?

Restaurant arches inspired the Golden Arches logo in McDonald's branding history.

In the 1950s, McDonald's restaurants used large yellow arches as prominent architectural elements. They were intended to make the buildings visible to passing motorists and to create a consistent visual identity for the growing chain.

Architect Stanley Clark Meston designed the early restaurant structures associated with the arches. The elements were physical parts of the buildings before they became an abstract graphic symbol used on signs, packaging, and advertising.

The logo's later M shape can make the design seem to have begun as lettering, but the historical sequence was the reverse: the letter-like mark grew from restaurant architecture. That connection explains why the symbol is called the Golden Arches rather than simply an M logo.
