Nice cover with both machine and clear hand cancellation. However, the cancel on the first stamp doesn't cancel the envelope as well and if you look closely you can notice not only the date is two years older from the rest cancels but the town is different too. This stamp, which was issued in 2007, has been used twice. The second stamp was issued in 1995.
