This souvenir sheet was issued on 12 September 1930 to commemorate the International Stamp Exposition (IPOSTA) in Berlin.
The stamps are the only gummed portion of the sheet, and they bear the Imperial Eagle watermark.
The stamps depict:
- 8+4 Pf — Aachen Cathedral and City Hall
- 15+5 Pf — Brandenburg Gate
- 25+10 Pf — Marienwerder Castle and Cathedral
- 50+40 Pf — St. Burkhard on the Main Bridge in Wurzburg
The stamps are of the same design as MiNr. 450-453, except with a different watermark.
Shown here is an admission ticket to the event, with bear-shaped punch.
