This just in from Serbia through Sasa Rakezic:

[Here is another ad from Politika daily newspaper, dated July 9th 1940. It's an announcement for a new edition of Politikin Zabavnik, a magazine that featured comics, and was coming out every Tuesday and Thursday. The ad is connected to a new Mickey Mouse story, and it says "if you want to see the rest of the story look for today's and all the succeeding issues of Politikin Zabavnik". The funny thing is that Mickey was shown singing a tune "Ala je lep ovaj svet" (This World is so Beautiful), which is actually a popular children's poem of the same title, written in the 1860s by a Serbian poet Jovan Jovanovic Zmaj. This is reflecting a constant wish to make Disney material be adjusted to the local readers. ]
