The "Four Centuries of American Art" pane was designed to be a collector's item and an educational tool, presenting a chronological and stylistic journey through the nation's artistic heritage. The selection of artworks is impressively broad, encompassing early colonial portraiture, the grand landscapes of the Hudson River School, the realism of the late 19th century, and the bold abstractions of the 20th century. By placing works like Rembrandt Peale's "Rubens Peale with a Geranium" alongside Franz Kline's "Mahoning," the pane highlights the incredible evolution of American artistic expression. The issuance of this set celebrated the richness and diversity of the nation's museums and collections, from which these masterpieces were drawn.
