By popular demand, the gummed deﬁnitive stamp “Lac de Tanay” (Mt. Jumeles) issued on 19th January 1993 is being reprinted. At the time, this stamp was printed in Swiss Post’s stamp printing works in Berne and was discontinued in 2002. Production technology has changed a great deal in recent years, and the printing m achines that were used in 1993 are no longer in use today. The new rolls were therefore produced using offset printing techniques at Joh. Enschedé in Haarlem (Netherlands). As a result, there are slight differences that are visible to the naked eye. Also, a different paper was used and hole perforation was employed instead of razor perforation (text: Swiss Post).
