Dear member federations,

The IOF was founded 21 May 1961, with ten founding members*. This year we
are celebrating the IOF 50th Anniversary with our 72 member federations.

Attached you’ll find the IOF Anniversary logo. Please feel free to use it in
your materials, especially should you have events that are organised around
the 21st May.
