Between 1907 and 1911, Caragiale studied Romanian heraldry and, to this goal, read Octav-George Lecca's "Familii boierești române" ("Romanian Boyar Families"). Many of the comments added by him to his copy of the book are polemic, sarcastic, or mysterious, while the sketches he made on the margin include portrayals of boyars being put to death in various ways, as well as caricatures (such as a blazon displaying a donkey's head, which he mockingly assigned to Octav-George Lecca himself). Several of the heraldic objects he created were destined for his own use. In June 1928, he raised a green over yellow ensign he created for the Caragiale family at his property in Fundulea. He also hoisted other symbols, including the flag of Hungary, which, he claimed, underlined his foreign origin.
