The P.59 Jolly was designed to meet a requirement for a standard trainer for the Italian national flying clubs. The prototype first flew on 2 February 1960 and was a high-wing monoplane with a nose mounted 95 hp (71 kW) Continental engine. It had a fixed tailwheel landing gear and seated two occupants side-by-side in an enclosed cockpit. The aircraft was later re-engined with a 100 hp (75 kW) Continental O-200 engine and the wing span was increased. The competition was won by the Aviamilano P.19 Scricciolo and only one Jolly was built.
