Official Catalogue Raisonne of Posthumous Renaissance Masterpieces


Global Art Authority, known as GAA, is a distinguished organization specializing in the authentication of posthumous first edition originals sourced from European museums. These precious artworks are meticulously crafted in bronze, pure silver, and pure gold, resulting in exquisite pieces of unparalleled quality.

To earn a place in GAA’s esteemed official catalogue Raisonne, a piece must have its origins traced back to the renowned Marinelli foundry collection in Florence, Italy. Furthermore, the casting must be derived from an original plaster mold, directly obtained from the marble or bronze masterpiece, retaining its original dimensions.

Within this official catalogue, GAA showcases masterpieces created by the most celebrated artists in history. These exceptional works are curated from the world’s most prestigious museums, including the Vatican, Galleria Dell’Accademia, Bargello Museum, Castello Sforzesco, Casa Buonarroti, San Domenico, Louvre, Cappelle Medicee, Piazza Maggione, Loggia dei Lanzi, Giardino di Boboli, Museo Capodimonte, Hermitage, Berlin Museo, and the Galleria Patatina. The roster of artists featured in this exclusive collection includes luminaries such as Michelangelo, Bernini, Giambologna, Donatello, Ghiberti, Canova, Cellini, and Verrocchio.

Each authenticated bronze casting is produced in limited editions, with a maximum of 12 originals and 1 artist proof. In contrast, castings in pure silver or pure gold are one-of-a-kind, making them truly exceptional and irreplaceable originals. GAA stands as a beacon of authenticity and appreciation for the timeless creations of the world’s greatest artistic talents.
