Old English SCRIPT, the real deal, mothholes and all, would be even more difficult to learn from, wouldn't it?
Perhaps an Old English-English dictionary is what you need?
Of course the script in such a book is typeset like modern print, not exactly an image of the original ink on parchment. But for studying Old English, I'm told Beowulf is the gold standard.
