The Austrian Post has issued a HB with the FEPA logo in the margins
The Österreichischer Post AG commemorated with special stamps the 100 years of the Republic of Austria, the 100 years of the first Civil Flight in Austria, the Old Post Carriages horse-drawn, the phila-Toscana Exhibition with FEPA Recognition in Gmunden and the Grand Duchy of Toscana. The FEPA logo was in the margins of the stamps sheets. Every sheet contains the 5 different motives four times each for a block of 20 stamps. Also were used their corresponding postmarks.
