Where can I find a map showing the sea level of Mediterranean Sea at end last Ice Age?

You can find maps in the research paper about last glacial Mediterranean coast lines: https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2011PA002223

For a smaller resolution you can also browse google images under the tag `Last Glacial Maximum Paleogeography Europe´. These can help you as a first insight. In addition, there is an interactive app which allows to change sea level of the earth to visualize past and even future shorelines:
