A polish cover with a volleyball stamp!

Thanks Andrzej for this cover from Krosno, a city in south-eastern Poland, about 40 km from Slovakia.

 The stamp is devoted to the women european volleyball championship held biannually. In 2009, this championship was held in Poland (cities of Bydgoszcz, Lodz, Katowice and Wroklaw). The winner was the italian team.

  As I am not an expert in Polish language, I can't understand the text on the cover (see below). If someone could help me, it will be a pleasure. Many thanks!

Merci à Andrzej pour cette enveloppe polonaise. Si quelqu'un pouvait me renseigner sur le texte présent sur l'enveloppe, je serais très satisfait. Merci par avance!
