As a teenager, Sówka, like many of his peers, went to work at the nearby Wieczorek coal mine. At first he worked above ground. Later, he did cutting and digging deep beneath the earth’s surface. The working conditions were harsh and unsafe and he felt like an insignificant cog in the enormous excavator.
Since he liked to draw as a youngster, he signed up for a course by the painter Zdziwlaw Krygowski at the community center for arts in Katowice. There Sówka learned the basics of studio drawing, perspective and composition. He initially painted with tempera.
Around 1955 he became a member of a society of about 15 amateur artists who, like him, worked in the local coal mine and lived in the Nikiszowiecz district. This mutually stimulating and inspiring group later gained national fame as the Grupa Janowska and consisted among others of Eugeniusz Bak, Ewald Gawlik, Teofil Ociepka, Boleslaw Skulik, Leopold Wróbel and Pawel Wróbel. Ociepka had with his demonic-occult paintings such a great influence on Erwin that he is often regarded as his artistic heir.
