Factory Models ( Serie Ouro )
After the explosion of Bossa Nova the Di Giorgio factory were producing 150 guitars per day across multiple sites in São Paulo. Guitars from this decade are known as Serie Ouro, for their golden label.
The Golden Label contains no year of manufacture unlike models from 1971 onwards. Some guitars contain unique additional labels denoting year such as:
- Série Ouro 1964
- Série Ouro 1965
- Homenagem 4th Centenario Rio De Janeiro ( 400 years since founding of Rio De Janerio )
- Jubileu 60 Anos 1908-1968 (60 Years of the Di Giorgio company)
Other unique additional labels from this period are:
- 3 Stars – sonoridade, perfeição, garantia (sonority, perfection, guarantee )
- Série Ouro DG
- GS Grande Sonoridade
During the late 1960s into the early 1970s, some models were sold in Brazilian department stores & music shops with unique Co-Branded labels under the title fabricação especial (Special Fabrication ). These include:
- fabricação especial SON CRISTAL (Crystal Sound)

These labels are usually associated with Serie Ouro guitars of the 1970-1971 period, although some Serie Artistica models with fabricação especial labels do exist.
