That's a very good price if the Moon and Daltrey are authentic - I would still check with Roger E. - but if you're planning to organize a Who display, keep in mind how you would want the piece to look, and how the two [apparently] good autographs would fit in with whatever Entwistle and Townshend sigs. you would find.
The Moon, Daltrey, and Entwistle are perfect as long as there is an indention from the blue ball point pen (and not a reprint of the signatures) I know its Authentic if thats the case! The Pete picture done in Sharpie,...not so sure about that one.
