Rank 25 documents the Maserati Tipo 61 Birdcage — the Trident's most radical 1960s sports prototype, named for its exposed tubular space-frame chassis that looked like aviary architecture wrapped in minimal navy coachwork. The Tipo 61 raced at Le Mans under Camoradi USA colours with number 7, a 2.9-litre four-cylinder engine mounted far back in the frame, and bodywork so sparse the cage structure remained visible — engineering theatre that conquered Sebring and challenged Ferrari's Testa Rossa hegemony even without an overall Sarthe win. Stirling Moss and Dan Gurney drove Birdcages to memorable victories across American and European circuits, and the model's lightweight philosophy influenced prototype design before monocoque construction made tubular frames obsolete. Wallimilist renders the navy three-quarter hero, green semi-circular arc, circuit outline, and MASERATI TIPO BIRDCAGE title exactly as the master PNG dictates — Sarthe prototype kicker, 13.626 KM callout, and curator copy on Italian space-frame folklore.
