One of the artists from the Shuster studio, John Sikela, started drawing Superboy stories in late 1946, and in 1949, when "Superboy" #1 debuted, Sikela became DC's primary artist on Superboy, and he remained the primary artist until he retired in 1958. A frequent collaborator was fellow Shuster shop alumni Ed Dobrotka. Curt Swan, who would later dominate Superman artwork for nearly 30 years, first drew a Superboy story in "Superboy" #5 (1949) and would continue to draw Superboy stories, on and off, for twenty years. The primary Superman artist of the 1950s, Wayne Boring, also contributed to Superboy.
