Sweden
1855 Issue 3s green, 3s yellow error of color, 24s orange
1869 issue 17ö gray
1880 Official Issue 10ö surcharge (proof only)

Sperati reproductions are known for the 1855 issue 3s green (2 types), 3s yellow error of color and 24s orange, the 1869 issue 17ő gray and the 1889 Official issue 10ö surcharge only for making inverted surcharge on 24ö. For his Sweden reproductions Sperati used genuine, common stamps including those with proper perforations, watermarks and correct cancels for the period. After applying protective coatings to the genuine cancel, he chemically treated the stamps to remove the design before printing his new design. See the mounted pages below that include some of Sperati's decolored stamps found in his archive as purchased by Carl Walske from his daughter, Yvonne Pochard de Sperati.
