Comparing different versions of the Monster Manual is tricky. that image from ISBNsearch.org, is the most legit scan, and it does have a TSR logo in the middle of the bottom. The upper right number does say "2003" which means this is a 2003 re-issue. This logo matches the first edition Monster Manual II, for which there is only one established cover art. The image is from the Forgotten Realms, wiki, without which I wouldn't have figured out how to see this. The 2016 on this means that it is a 2016 re-issue. These are legit, but not especially valuable.
