In the 1910s, McManus launched Their Only Child, essentially a continuation of the Newlyweds, but the cartooning has greatly matured. The settings and poses start to look even more archetypically McManus-like, the storytelling more complex and accomplished. The wife still looks the same, of course; McManus clearly cut his teeth tracing Gibson Girls as a lad, and the same graceful profile would appear in his strips for all of his career. The child has progressed only slightly; where his dialog consisted solely of "da-da-ta-ta" in the Newlyweds, he's added "Wow!" to his vocabulary in the new feature.
