Lot of antique elementary school English grammar, online reading, and writing and history textbooks including McGuffey's 1867 Eclectic Reader
You could certainly use these books for decorative functions. As a background for a photo shoot, perhaps to show your appreciation the history of American education. You might us them in the background of a Zoom meeting to suggest that you are much older than in fact you are so that people will be astonished at how youthful you look at age 175.
Or you could (also) read them and learn at great deal about the history of American education.
(Just a note: neither photographing nor reading these reads will create eternal youth.)
