The 10c stamp is from 1970 Physicians issue honoring bacteriologist Alexandre Yersin.

Alexandre Emile Jean Yersin (September 22, 1863–March 1, 1943) was a Swiss and French physician and bacteriologist. Along with Shibasaburo Kitasato, he is remembered as the co-discoverer of the bacillus responsible for the bubonic plague or pest, which was later re-named in his honour (Yersinia pestis).

The 180c stamp is from 2003 Medicinal Plants issue showing Malva Sylvestris,which is a species of the Mallow genus Malva in the family of Malvaceae and is considered to be the type species for the genus.

Mucilage is present in many of the Malvaceae family,especially the fruit and were employed medicinally, as demulcents and emollients. The seeds were used internally in a decoction as a demulcent and diuretic and the leaves made into poultices as an emollient for external applications.

#075 Switzerland...Thanks Sara!

The se-tenant stamps on this nice cover were issued on Jan.06,2010 to celebrate the 100 years of Basel Carnival Committee and the biggest carnival in Switzerland.

The Carnival of Basel (German: Basler Fasnacht) takes place annually between February and March in Basel. It has recently been listed as one of the top fifty local festivities in Europe.In this year Basel Carnival starts on 22 February with the Morgenstreich procession.

Unlike the Carnival celebrations held in other cities on the Rhine (such as those in Cologne, Mainz and Düsseldorf), the Basel Carnival displays a clear separation between participants and spectators.

The 3 stamps bear the enigmatic titles "Spalentor", "Rathaus" and "Munster".
