Where can I find an old book, "The One-Eyed Griffin, and Other Fairy Stories" by Herbet Escott Inman to buy?

My Nana was telling me about a book she was read to when she was a little girl that was her favourite called, "The One-Eyed Griffin and Other Fairy Stories". I did some searching on the internet to find out the author who is 'Herbert Escott Inman'. I think it also was first published in the 1920's. She told me that she'd love to have a copy so i thought if I can try and find a decent copy of this book I can buy it and suprise her at Christmas time :) which I'd really love because she does so much for me. Pleeease help me out!! I've searched and can find next to nothing :(.
