To mark Saint Valentines Day, Polish Post has produced both a stamp and a postcard. The stamp, designed by artist Magdalena Blazkow is a synonym for happiness and prosperity - the clover leaf. This small work of art has been printed on fluorescent paper, with a circulation of 1,000,000 stamps.
The first day cover bears the date and heart-shaped leaves. In addition, the envelope has the words of George Sand: "There is only one happiness in life - to love and be loved."
