意第緒語
Kol Mevasser (Yiddish: קול מבשר) was a Yiddish language periodical that appeared from October 11, 1862 into 1872. It is considered by Sol Liptzin and others to be the most important early Yiddish-language periodical (although by no means the first: the short-lived "Die Kuranten" in Amsterdam pre-dated it by centuries).
