[Publib] Library sign

[Allison Angell]

Hello-
We are looking for a new sign to replace our old, heavy sign that we used to advertise storytimes outside the Library.  We are leaning towards a permanent outdoor sign that would be used to announce all of the events going on at the Library each day.  We want it to look nice (dignified, not cutesy), be a challenge to vandalize, and have the ability to change the displayed information on a regular basis.  Do any of you have such a sign at your library?  Where did you get it, and what is it like?  Any ideas are appreciated. 
Thanks,
Allison
