I KNOW ONLY A FEW WORDS IN BULGARIAN SO I COULDN'T UNDERSTAND THE EXACT MEANING OF THIS BOOK. IT SEEMS IT'S A BOOK OF SONGS OR POETRY. FROM THE TITLE, I UNDERSTAND SOMETHING LIKE " THANK YOU, RUSSIAN BROTHERS" (DEAR BULGARIAN/RUSSIAN VISITOR, TELL ME IF I'M WRONG) AND FROM THE DRAWINGS... WELL... REVOLUTION BRINGS HAPPINESS? WAR IS BEAUTIFUL? (YOU CAN CLICK ON THE PHOTOS TO SEE WELL)
