The display was launched in the Polish capital's Świętokrzyski Park to mark the United Nations' World Children's Day.
Some 30 posters featuring photos of children taken hostage by Hamas were arranged on park benches and around the statue of the Polish-Jewish doctor, writer and child advocate Janusz Korczak, state news agency PAP reported.
Each poster was accompanied by a doll, and a note saying that "On October 7, some 200 innocent Israeli citizens were abducted and kidnapped from Israel to the Gaza Strip."
The note added that the whereabouts of the hostages remained unknown.
Adam Koren, who organised the exhibition, told the PAP news agency that more than 30 children were being held captive by Hamas and that similar exhibitions were being staged in various other places around the world.
Israel's ambassador to Poland, Yacov Livne, visited the display and called on the Red Cross and the United Nations International Children’s Emergency Fund (UNICEF) to "demand an immediate release of all Israeli hostages, especially Israeli children, held hostage by terrorist organisations."
The war between Israel and Hamas broke out when the Palestinian Islamist group launched attacks from the Gaza Strip on October 7, killing 1,400 people and kidnapping more than 200 as hostages, according to the Israeli government.
Israel has since been bombing Gaza, as well as mounting a ground assault on the territory, killing 13,000 people, including more than 4,500 children, according to Gaza's Hamas-run health ministry.
On Monday, the International Committee of the Red Cross said its head would meet with Hamas, raising hopes that a deal could soon be agreed that would involve Hamas releasing hostages from Gaza in exchange for pauses in fighting, the British broadcaster BBC reported.
