Eventueel voor te leggen aan de club waarbij men aangesloten is

Hallo,

Ik probeer samen met een paar afdelingen in Noord-Holland een lezing van Guillermo Riviera te organiseren. Ik kreeg van hem onderstaande informatie. Wij mikken op een presentatie op vrijdag 17 augustus.

Vriendelijke groeten,

Wiebe
