Experiencing anything in person hits differently, I'm sure you'd agree? Listening to live music, viewing art, being at your child's birth, hanging out with friends.
With music and art in particular, you're not limited to low fidelity reproductions when you witness the real thing. It must be a fairly common desire given that concert halls, museums, and art galleries exist.
In this particular instance, each impression of The Great Wave is different—actually unique—because of the way they were mass produced. So you might want to see a different one, or maybe try to see as many as you can to compare them. Also, in person you might be surprised by its size.
You've seen The Great Wave, the Mona Lisa, etc. but have you seen it?
