After World War II, Teague penned a design for a pre-Henry J economy car for Kaiser Motors. In 1947 he joined the General Motors design studios headed by Edmund Anderson. Starting as an apprentice stylist and eventually graduating to the Cadillac advanced design group, he also worked on the 1950 Oldsmobile Rocket. The 1950s "saw some of the most beautiful and some of the most outlandish vehicles" and the head of the design department at General Motors liked chrome on cars. Teague described how two sets of overlay designs were made for Harley Earl to choose from. Both chrome trim sets had been put on one Oldsmobile prototype by mistake. Earl saw it and ordered it produced that way although the stylists were horrified.
