This set was issued to benefit the victims of catastrophic damage to the city of Semendria.
The stamps depict Semendria fortress (MiNr. 46 and 49) and refugees (MiNr. 47 and 48). The stamps are of the same design as MiNr. 50-53, but with different colors and surcharges.
MiNr. 47 can be found with two plate flaws — missing the Cyrillic “S” (MiNr. 47 I) or “G” (MiNr. 47 II).
