Gulf Powder Blue — 3 museum-grade prints in this palette. Gulf Oil's powder blue and orange became shorthand for 1960s and 1970s endurance glamour through JW Automotive's Porsche and Ford campaigns at Le Mans — later immortalised in Steve McQueen's Le Mans film and countless homages. The #20 Porsche 917 and #6 Ford GT40 roundels visible here echo that era's most recognisable Gulf pairings without claiming affiliation to Gulf Oil, Porsche AG, or Ford Motor Company. The Porsche 917 Langheck represents the moment Porsche transformed from contender to dynasty at Le Mans — back-to-back overall wins in 1970 and 1971, with the 1971 distance record becoming motorsport folklore. Gulf Oil's powder-blue and orange livery, managed by John Wyer Automotive Engineering, is among the most licensed colour schemes in racing history. The Porsche 917 in Gulf livery is among the most reproduced endurance-racing silhouettes in poster history, tied to Porsche's first outright Le Mans victories in 1970 and 1971. Ayrton Senna's 1988 season in the McLaren MP4/4 — eight wins from sixteen rounds — remains a benchmark for Formula 1 dominance.
