Addressing the opening ceremony, a local parish priest, Friar Ivica Jagodić, said that the exhibition was inspired by the book "Mama, Ne vidim Nebo" ("Mum, I can't see the sky" in an unofficial translation) by writer Ani Galović.
The book gives available information about the 34 children who were killed or went missing in Vukovar and its environs when this town was under the siege and later fell into the hands of the occupying forces, that it Serb rebel units supported by the Yugoslav People's Army (JNA), according to the explanation given by Friar Jagodić.
Some of those victims were babies while one of them, Tomislav Baumgartner, was killed seven days before he turned 18.
The exhibition, designed by Žaklina Kurmaić, includes illustrations prepared by German artist Vladimir Köter.
