Let's say a Jew hung a map or a document on the wall on Shabbos.
For the purposes of this question, let's assume that this was a desecration of Shabbos (presumably because of the prohibition on completing the construction of something on Shabbos).
Would another Jew be permitted to look at this map or document after Shabbos?
Or would this qualify as impermissibly benefiting from an act of Shabbos desecration?
