Issued in 1951, this elegant three-stamp set from Monaco honors St. Jean-Baptiste de La Salle (1651–1719), founder of the Institute of the Brothers of the Christian Schools and patron saint of teachers. The designs by J.-E. Lorenzi reflect Monaco’s postwar artistic modernism, with minimalist line drawings of De La Salle and his students—symbolizing education and faith. The set features denominations of 1 franc (red), 5 francs (black-brown), and 15 francs (blue). These stamps are highly regarded among collectors for their cultural depth, modernist simplicity, and finely executed intaglio printing.
