Netherlands #640

I recieved this interesting and nice letter from the blogger Cees Prins
(Netherlands). I like his blog very much. Have a look! http://stampsandchickenthings.blogspot.com/
On the cover you can see an official personal stamp (2007) of Gees Prins (0.44 Euro) with his own logo
and the stamp "80Years of NVPH (Dutch Stamp dealers assоciation) 2008.
Thank you Gees, it is a brilliant thing!
