IMO AND FWIW....
Its not helpful to use maximalist terminology ("for certain" "greatest gift" etc) when discussing anything, particularly aesthetics and education and child rearing.
One great gift would be "Alfred Stieglitz Camera Work" ... full of beautiful images, mostly printed for reproduction by Alfred Stieglitz himself. It's especially valuable IMO because we spend so much time worrying about modern tech (such as Kodak Paper and the lenses we lust for and images presented to us online) and almost never do we see foundational photograpic beauty, like that in this affordable Taschen book.
