The reverse reproduces the obverse design in mirror image, printed in black intaglio, with the central text panel overlaid in blue guilloche underprint. The mirror-printed allegorical figures, cherubs at the four corners, and the Royal Arms at bottom centre remain visible in the reversed composition, with blue flourishes reinforcing the central cartouche. |

The Banque Nationale de Belgique was only a year old when this note entered circulation — the bank was founded in 1850, and the 50 Francs was among its earliest emissions. Léopold Wiener was primarily a medallist and engraver to the Belgian royal court, not a commercial banknote designer, which gives this issue an unusual sculptural quality in its intaglio work that later BNB notes largely abandoned in favor of more conventional security engraving.
Pick 4 is genuinely rare at this date. Early Belgian notes suffered heavy attrition through redemption and destruction, and the 1850s issues are among the most seldom encountered in any condition.
