Well no, not pieces of plastic, but stone seals, copper tablets, pottery and, surprisingly, one large sign board, which was found buried near the gate of a city.
Nejsou to kousky plastu, ale kamenná pečetidla, měděné tabulky, keramika, a překvapivě, jedna veliká deska s nápisem, která byla nalezena zakopaná poblíž městské brány.
