Blueprint Line Grey — 3 museum-grade prints in this palette. The Alfa Romeo Tipo 33 programme represents Autodelta's most ambitious competition era — a V8 prototype family that evolved across five seasons while Porsche and Ferrari traded outright Sarthe honours. Carlo Chiti's engineering, the green Quadrifoglio clover, and Alfa Rosso livery became shorthand for Italian prototype craft that valued beauty and night-stint courage alongside lap-time arithmetic. Frazer Nash occupies a singular niche in British motorsport — a specialist builder that prioritized driver engagement and lightweight craft over factory scale, producing cars in numbers small enough that every Le Mans entry feels like a documented event. The Le Mans model name itself declares circuit intent, and the marque's Bristol-engine partnerships delivered reliable power in a package that punched above its displacement on twisty Sarthe sections even when Mulsanne straight speed favoured larger prototypes. Citroën's BX 4TC programme arrived at the twilight of Group B — a front-engine turbo layout that competed against mid-engine rivals engineered under the same PSA umbrella as the dominant Peugeot 205 T16. The car's brief WRC career and limited production run made it a rare Martini-liveried curiosity rather than a championship weapon, yet its BX silhouette and French ambition narrative occupy a distinct place in Group B folklore.
