In the 60´s my grandfather organised bike races in the north of the Netherlands. At the time my mother was a teenager and many of the day´s professionals cyclists visited their house. On one of these visits made by Wim van Est he gave my mother a post card and signed it for her.
My mother found the card last week and gave it to me.
Wim van Est is very well known in Holland for the way he lost his yellow jersey in the Tour the France. http://www.myshavedlegs.com/2007/05/in-search-of-wim-van-est.html
