Jiří Winter-Neprakta created children's book illustrations, drawings and comics for children. He understood the children's world of fantasy. He devoted himself to many other children's genres. For example, he was the creator of many games for children. This part of his work is not as well known as his porcupine cartoon jokes or book illustrations. In his work we can find mazes, fairies, ghosts, which, however, are not scary, on the contrary, they are cute, funny, have a clear and good character. Children do not have to be afraid of them, but they can support them, connect with them, because they are very similar to human beaings. His favorite subjects included animals and fairy tale characters.
