Yeah !… I was waiting for it during a week and finally it arrived today!… a card from the Netherlands from my friend Erik (you see the good thing of advise your friends about your hobby). Here it is:
Danku Erik !
The bad thing is they guy of the post office put another thing over the stamp, but I could rescue it with hot water, now I have the stamp all visible and you can even see the mark on the stamp with the name of the city. Here I show a picture of some of the stamps of this serie:

Stamps issued with the new prices on January of 2007, each stamp has a dutch symbol on it. The one I got is the blue one with the skate that in dutch is called "Klapschaats"... I learned a new word cause when I saw this first I tought it was the name of the guy who designed the stamp.
Inside there was also a stamp of the Queen Beatrice with the value of 39 cents, so this ones is before they changed the rates of internal mail to 44 cents.

The card took 9 days to arrive and it travelled 916.75 Kilometers…
