Cabrera's bronze Palmarius sculptures (I & II) are conceptually linked to his Golden Skull Palmarius, first exhibited in November 2022. That presentation, held at the Top of the Rock in Rockefeller Center, New York, marked a significant milestone in Cabrera’s career. The title translates to "Masterpiece", and these table-top sculptures are spectacular in person, with richly detailed symbols and writing rising from the skull's biomorphic form.
