It probably isn’t a good idea to post signs on your library that read “library closed” when that’s not what you mean. Removing the paragraph at the bottom (that no one is going to read anyway) would have freed up the space to include “will be” inline.

These signs on signs are particularly unfortunate because, even though the overall design of the sign is lacking, the visual design is perfectly okay.

The signs’ nice visual design is also rendered less effective by the “let’s laminate these with packing tape” implementation. It detracts from the professionalism that nice looking signs might otherwise express.
