Iuventus: ephemeris in usum iuventutis studiosae
This Latin-language newspaper was published in Hungary in 1910-1945. An antiquarian shop offers issues from 1910-11, 1911-12, 1913-14, and 1937-38 years.
It would be great to get access even to one issue, but it seems it wasn’t digitized by Google Book, and WorldCat directs to only library in Budapest.
P.S. Article Hajrá, Iuventus! (in Hungarian) tells more about this newspaper.
