The postage stamp features a detail of a Baroque fresco from Troja Castle, one of the most beautiful historic residences in Prague. This exceptional Baroque complex is one of the Czech capital’s most significant landmarks and is renowned for its rich ornamentation and impressive architecture. The artist behind the depicted motif is Abraham Godyn, whose works are among the pinnacles of illusionistic Baroque painting. Through his masterful use of light, perspective, and the human figure, he created a striking sense of space that blurs the line between real architecture and the painted image.
