Topical: The Moustache

In 1990 Poland honored its newly-elected President, Lech Walesa, with this commemorative 1700 zloty stamp.

From wikipedia, "Lech Walesa (born September 29, 1943) is a Polish statesman, dissident and Nobel Prize laureate, who served as the first democratically-elected President of Poland from 1990 to 1995."

Here are two stamps depicting medical missionary, humanitarian and Nobel Prize winner Dr. Albert Schweitzer. The Polish stamp (Sc #2758) was issued on September 26, 1986, and the West German stamp Sc #1160) was issued on January 15, 1975.

From wikipedia, "Albert Schweitzer (1875-1965) was an Alsatian polymath (person of encyclopedic learning). He was a theologian, organist, writer, humanitarian, philosopher, and physician."

Here is a 2020 French issue celebrating photographer Felix Nadar who sports a significant moustache in this 1865 revolving self-portrait. The second stamp wherein Nadar sports a big grin is my favorite of the set.
