At the 1st International Stamp Exhibition in Vienna (Wiener Internationale Postwertzeichen - Ausstellung) 13.-20. The stamps were stamped and imperforated on paper with and without glue. 20 types of stamps were printed. Stamps were printed in blocks of 16 pieces (4x4). They had no payoff value. Use on letters has always been a philatelic character.
In 1890 another international exhibition was held in Vienna (20.4. - 4.5. 1890). Even at this exhibition were printed stamps with a picture of the issue 1850 - this time type III. Many species have been released with or without serrations. On multicolored papers with and without glue.
