thumb|Chevrolet plant in Tarrytown, NY, c. 1918 Chevrolet first used the "bowtie emblem" logo in 1914 on the H series models (Royal Mail and Baby Grand) and The L Series Model (Light Six). It may have been designed from wallpaper Durant once saw in a French hotel room. More recent research by historian Ken Kaufmann presents a case that the logo is based on a logo of the "Coalettes" coal company. An example of this logo as it appeared in an advertisement for Coalettes appeared in the Atlanta Constitution on November 12, 1911. Others claim that the design was a stylized Swiss cross, in tribute to Chevrolet's home country. Over time, Chevrolet used several different iterations of the bowtie logo at the same time, often using blue for passenger cars, gold for trucks, and an outline (often in red) for cars that had performance packages. Chevrolet eventually unified all vehicle models with the gold bowtie in 2004, for both brand cohesion as well as to differentiate itself from Ford (with its blue oval logo) and Dodge (who has often used red for its imaging), its two primary domestic rivals.
