Hmm, not quite. 542569 is taller and a teensy bit wider, but has less pixels. 522702 seems the clearest and has good color balance, but the resolution isn't as high. 523015 is obviously cropped too much. Unfortunately, none of them is a clear winner as a parent post. I'd recommend just leaving it as is, until a higher quality scan comes along.
