About this mug
The RML P39 – Signature Mug celebrates one of Britain’s most extraordinary modern hypercars, beautifully illustrated by Joel Clark in his distinctive style as part of the Signature by Sipfull collection. The RML GT Hypercar, internally known as the P39, is a heavily reworked Porsche 911 Turbo S inspired by 1990s Le Mans prototypes — producing 907 hp, 1,000 kg of downforce and 0–60 mph in just 2.4 seconds. Here it’s captured at Supercar Fest with clarity and character.
Joel’s artwork spotlights the P39’s dramatic bodywork and purposeful aero through bold colour, sharp contrasts and layered tones that convey speed, tension and precision. This mug turns a million-pound British engineering masterpiece into a striking yet functional piece of art, perfect for those who appreciate cutting-edge Porsche-based performance.
This mug comes with a 1-Year Print Guarantee, ensuring the artwork remains bold, sharp and long-lasting.
