Children's artistic expression is essential for their expression and communication. Children are artistically expressing themselves spontaneously and from an early age. However, lately, they are often being exposed to the influence of mobile phones and other media. It is absolutely impossible to escape from the information that is constantly in flux and is thus easily accessible to children, but it is crucial to control it as much as possible, so that quality and age-appropriate information reaches children. Children of preschool age spend more and more time with mobile phones in their hands, which is visible in their artworks, which are analyzed in this paper. In the analysis of children's artistic works, we wanted to find out how visible the influence of mobile phones is on children's artistic expression. The analysis was carried out on 10 papers, out of a total of 50 collected. It is important to note that the collected works were created during free activities in kindergarten, without encouragement, completely spontaneously. The analysis found that the influence of mobile phones is visible in children's artworks, that boys use mobile phone motifs in their artworks more often than girls, and that there are almost no templates in the analyzed works.
