I gave a copy to my teacher as a holiday present, and of course I thumbed through before I wrapped it.
The pictures alone are worth the price of admission, but the the whole thing together is worth much more.
I can’t imagine any harpist I know who wouldn’t find it delightful.
As Saul says, go buy a couple copies.
The only single thing I’d love would be if it were available as a library bound edition- I would have purchased one for our local library on the spot.
