"Mordillo" is the pen name of cartoonist Guillermo Mordillo, born in Argentina in 1932. He is best known for his cartoons, which feature a unique blend of humor, absurdity and a distinctive style. His cartoons focus mainly on minimalist design, often showing only a few details. The figures in his cartoons usually have a spherical shape and are depicted with big eyes and a mischievous smile. Mordillo's works often deal with everyday situations and interpersonal situations, but always with a humorous twist. In the process, the viewer often finds surreal elements where he can not help but smile.

Mordillo's art has received worldwide recognition and his cartoons have been published in numerous magazines and newspapers. He self-published several books with his drawings and his works were shown in exhibitions around the world. In 2019, he passed away at the age of 86.
