Looks good to me, but it looks like it's missing Phil Collen's signature. And it is signed by Vivian Campbell and not Steve Clark. Shouldn't be too expensive. Here is a copy that I bought signed with the right lineup:
I paid $5.00 (Five) for mine and I sold it for $200.00 a few years later. This was before it become real popular to collect music autographs. The one that you posted I would pay around $100.00.
