Two young girls, likely sisters, are playing with a wooden toy cash register. One girl is fair-haired with a small ponytail, wearing a pink dress and white long-sleeved undershirt. She is using a red mallet on the toy cash register. The other girl has dark hair in braids, also wearing a pink dress and white undershirt. They are in a room with white shelving containing baskets and toys, including a yellow play slide. The location is a playroom in Sofia, Bulgaria. Other people are visible in the background, likely adults supervising the children.
