I love this hallway display I ran across at one of our schools (to be honest it is the hair on Nina Simone). After looking at it several times I actually thought it was pretty clever.
Here is a hallway display that can be left up for literally two months. It can be left up for February (which was when it was made) for Black History Month and then for March for Women's History Month. I might just change out the title of the board to keep it current.
If you have friends (like I do) that dislike having to change out their bulletin board (not me...I like a good arts and crafts project) this one would be a perfect one to borrow for a month (or two).
