Vedem’s early artwork reflected subjects typical for teenage boys in 1940s Central Europe, including depictions of ships, pets and families. But the renderings evolved to reflect Terezin’s harsher realities, with later drawings depicting subjects such as a family boarding a ghetto-bound train, an old person suffering from illness and a guard holding a gun. While much of the work was created by editor and artistic prodigy Petr Ginz, the identity of many of the illustrators remains a mystery because much of the work was unsigned.
