The Secret Assembly of Vostitsa by Kostas Klouvatos

The Secret Assembly of Vostitsa by Kostas Klouvatos (1923-2007)
Greece Stamp Issued 1975
Folk Art

This is an engraving by an artist who is more known for his sculptures.  Klouvatos' work during the 1960s was focused on critical points in the history of Greece.  This one focuses on 26th September of 1820, where all dignitaries of Peloponnese (Moreas) gathered, and Pappaflessas (a Greek Revolutionary hero) is trying to convince them that a revolution should be launched.  Klouvatos attempted to combine elements of Greek tradition with various styles through the ages, thus accounting for this depiction of Pappa Flessas.  The stamp was part of a series that commemorated the 150th Anniversary of the death of Papa Flessas.

Papaflessas by Adam Friedel

Papaflessas, Greek Revolutionary Hero in Maniaki 1by Adam Friedel (1825)
Greece Stamp Issued 1975 

Papaflessas (Grigorios Demetrios Flessas, 1788-1825) was Greek priest and patriot who led a revolution for independence. During the Greek War of Independence Papflessas was Minister of Internal Affairs and Chief of Police, until he was killed during the Battle of Maniaki, in which he led the Greek troops against Egyptian forces led by Ibrahim Pasha. The stamp derives from a plate from a series of twenty-four portraits of figures related to the Greek War of Independence, by the Danish painter Adam Friedel.

Michelangelo - The Delphic Sibyl from the Sistine Chapel

Michelangelo (1475-1564) - the Delphic Sibyl from the Sistine Chapel (1512)
Grenada 1c Stamp Issued 1975
Painting in the Sistine Chapel, Vatican City

In 1975, Grenada issued a series of stamps to commemorate the 500th anniversary of the birth of Michelangelo.  This is one of the most famous images from the Sistine Chapel, being the Delphic Sybil.  Sybils are part of Greek mythology, who were prophets in many locations in legendary tales.

It is said that Michelangelo did not enjoy the commission that was given to him - to paint the huge ceiling of the Sistine Chapel took 5 years.  However, this work is his most monumental and well regarded feat that gained him fame.

Eugene Lansere - Building the Metro

Eugene Lansere (1875-1946)  - Building the Metro (1935) 

(now a mosiac in Metro station in Moscow, Komsomolskaya 1935)

Russia Stamp issued in 1975

This Russian painting is quite unusual in that the art work adorns the wall of a subway station in Moscow's Metro subway system in the form of a mosiac tile display.  The Moscow Metro is incredibly ornate as it was designed to last for a long time - the leaders of Moscow must have decided to spend up big on this once in a lifetime construction project.

According to Wikipedia, the Moscow Metro is the busiest subway system in the world, except for Tokyo.  The painting in this stamp is typical of much of the socialist realism art that exists on many stations throughout the system.   It also dates back almost as far as the London Underground, as the Moscow Metro began operation in 1935.
