The cartoon is based on The Songs of Bilitis by French poet Pierre Louys, and has received three other Bulgarian and international awards over past two years. Bulgaria's Culture Ministry will propose the inclusion of the ancient town of Plovdiv, the Forty Holy Martyrs Church of Veliko Turnovo, the tomb at Bachkovo monastery and the Thracian tomb located near the village of Alexandrovo in UNESCO's World Heritage List.
