There are two known perfin patterns used in the Faroes; both of them related to the sale of oil and petroleum products. The "D.D.P.A." (Det Danske Petroleums Aktieselskab) pattern was used from 1925 to about 1930. However, great care must be taken that "D.D.P.A." items have Faroe cancellations as the same pattern is very common used in Denmark. Starting in 1930, the Valdemar Lützen company took over the oil distributorship and the perfin became "V.L." The "V.L." perfin can be found at least up through the early 1980s. On Danish stamps (1930-1974), the "V.L." perfins have a premium value if with a decipherable Faroe cancel. Other examples are usually available; please request approvals. All Scandinavian perfins are available on approval.
