In this post I just want to present two covers from Cyprus just to show the rates for domestic mail. For a normal envelope weighing 20-100g (1st envelope) the rate is o.34 euro plus the Refugee Fund stamp and for a registered envelope 2.05 euro plus the Refugee Fund stamp.
The 1st envelope was mailed from Larnaka to Nicosia and the 2nd one from Aradippou Post Office to the same address.
The first envelope was machine canceled and the S24/2009 commemorative slogan is used celebrating the World Post Day 9.10.2009. This slogan was used from the 5th of October until the 9th of the same month. The same slogan is used every year for this event.

Thank you Daniela for this excellent cover. The full 2006 Eurasian or Common Spoonbill (Platalea leucorodia) set is used. This species can be found in marshy wetlands in North Africa and in southern Eurasia. Most birds migrate to Africa for the winter. There are three subspecies. It feeds on fish, amphibians and crustaceans. It is a protected species.

I will now show you another of my self-made maxi cards. I used a 2009 stamp from Cyprus set Domestic Fowls.
Two things are wrong with the maxi card. The most visible is the quality of the postmark. This is due to the surface of the card which is not suitable for the ink used by the post office.
The second mistake is that while the stamp shows a Domestic Turkey the card shows a Wild Turkey (Meleagris Gallopavo) although they both are the same species.
Wild Turkey and specifically one of its six subspecies M.G.Gallopavo (South Mexican subspecies) is the ancestor of the domestic one. Wild Turkey is native to North America and it is omnivorous.
