A new, improved library alarm sign

Last year I wrote a post about my library and their alarm sign. Well, I guess the sign was a bit too inconspicuous because one day recently we walked in and saw a newer, larger sign in its place.

Before

Too plain?

After

Sign? What sign?

The new sign is bigger but no less polite than the original. Also, notice the pretty border around the white?  And the stand itself is sturdier. What are the odds that some people will still walk by this while the alarm sounds?
