The Great Moravian Rulers - a set of four stamps, placed on the lower part of a presentation sheet. They picture portraits of important Great Moravian rulers (from the beginning of 9^th century) - Pribina, Rastislav, Koceľ, Svätopluk. These Great Moravian rulers were from the Mojmír's dynasty and they founded the original west-Slavic state, extended the territorial boundaries, and cultural expansion. They are pictured with the Great Moravian map at its greatest times. The map was designed based on the findings of the academician Ján Dekan, who has also included a shield, depicting a falconer, which is a reproduction of an archeological find.

Koceľ (9th century) - was Prince of the Principality of Blatno (around 861-876), the son of Prince Pribina of Nitra. He actively participated in the development of Blatno while his father was alive, he succeeded his father on Prince Pribina's death. Originally, he was a vassal of a Frank king, but around 869 he united with Great Moravia and he strengthened its national and Christian independence. He was a supporter and protector of Slavonic writings (Frizínske manuscripts), and played an important role in the development of Christianity. He delayed Constantine-Cyril and Method in Panonia in 867, on their return from the mission in Great Moravia. The Thessalonian brothers trained fifty students in Blatnohrad and gained Koceľ for their idea of propagation of Slavonic liturgy.
