The first draft of this livery dates back to the early 2000s. The very first idea was to combine a white and red field to support a black clover, like the colors of an ancestral imaginary Irish family (the O'Baker family, indeed)
The idea caught on: here's a modern take on an O'Baker Motorsports livery. I wanted an organic, asymmetrical side reminiscent of a worn banner, and the initial black clover turned silver.
Originally, the brilliant driver Amy Walker was under an exclusive contract with Subaru, and affiliated with the Mythos team. After Mythos became the Pagani factory team in the early 2000s, Walker switched to OBK-Subaru and then to Porsche when the Irish team signed with the manufacturer from Stuttgart.
