… is from page 94 of Melanie Kirkpatrick’s 2016 book, Thanksgiving: The Holiday at the Heart of the American Experience (link added):
[Thomas] Nast was an immigrant, having arrived in America from Germany when he was six years old, and “Uncle Sam’s Thanksgiving Dinner” reflected what Nast saw as the immigrant’s passionate affection for his new country and commitment to its democratic values….
At the head of the table stands Uncle Sam, who is carving a turkey. Around the table are seated Americans representing an array of races and religions, identified in many cases by their national dress. Among the guests are an African American family, a Native American, a Chinese man with a long queue, an Irish American couple, a Spanish woman wearing a mantilla and holding a fan, a bearded Muslim with a fez on his head. Nast presents the people in this portrait respectfully, not as caricatures. His message is that every American has an equal right to sit at the Thanksgiving table.
