Earlier this week, NOTOS 2021 IREX details were finalised. They were subsequently agreed between the FEPA Consultant and the OC. The IREX was later uploaded on the exhibition website (Menu: The Show > Regulations) along with all the FIP and FEPA regulations observed in NOTOS 2021.
You can get the IREX elegant booklet directly from here (4.2 MB). When you read it, you will realize that it reflects everything the OC has so far promised: Innovation, technology and imagination, along with high philatelic standards, low participation fees and respect to the Philatelic Literature exhibitors.
