Cleanup 

 known in Croatian as Juraj Julije Klović, was an illuminator, miniaturist, and painter, of Croat origin, who worked in Italy.[1] - removed and replaced by the earlier version due to several facts
 it was mentioned later that Croats thinks that Clovio's 'real' name was Juraj Julije Klovic - no need to say it twice
 Croat origin - rather his birth place is in today's Croatia. He was of Macedonian lineage
 who worked in Italy - impprecise and incorrect; he was educated(trained) in Italy, lived in Papal State and Venice, died in Rome and belonged to the Italian Rennaisance painters circle

 about non-existent Kingdom of Croatia - full report given above

 removed Vatican City post stamp: Christmas 1998 – 500th anniversary of the birth of Julius Clovius Croatus as a valid reference due to the fact that this 'reference' is a chat site

 moved http://www.posta.hr/main.aspx?id=193&idmarke;=312 from International to the Croatian references

 removed completely Under Clovio's bust, beside his name, is written the name of his homeland: Pictor de Croatia[1] (Painter from Croatia). as a false claim. Also, reference [1] has another false claim Klovic used to sign himself as GEORGIVS JVLIVS CLOVIVS CROATA which disqualifies  completely as a valid reference.
