Step 1 : Introduction to the question "Which magazine popularized the modern image of Santa Claus?"
...The modern image of Santa Claus was largely popularized in the mid-19th century by political cartoonist Thomas Nast through a series of illustrations published in Harper’s Weekly. Beginning in 1863, Nast depicted Santa as a cheerful, bearded man with a round belly, a red suit trimmed in white fur, and a warm demeanor rooted in generosity and goodwill. These widely circulated images helped standardize Santa’s appearance in American culture, laying the groundwork for the version later reinforced and spread globally through advertising.
