What is an autograph on an original brochure?

An autograph on an official brochure is a collector's item that combines original promotional material from a team or manufacturer with the authentic signatures of the racing drivers. It stands out from more common memorabilia due to its distinctly professional nature: official brochures are distributed in exclusive contexts such as paddocks, events, and private presentations, making them rare and contextualized items. When the signatures are from two drivers from the same team — as in this case — the collectible value is further amplified. In addition to these elements, the MTM Letter of Authenticity (LOA) is included free of charge, with the option to add a COA for international protection.
