You are encouraged to have the autograph authenticated by any preferred third-party service. Our impeccable track record reflects our unwavering commitment to authenticity. To preserve quality, each autograph is secured in a BCW hard top-loader immediately after signing, handled with professional gloves to avoid any fingerprints, and remains safely encased except during photography. We extend our sincere gratitude to Donald Trump for generously contributing his time and autograph to support our charitable mission.
