Your local library will have numerous books to help teachers do displays
and bulletin boards, etc. We have numerous ones and we're only a town
with 8,000 people. They are full of inovative, inexpensive, dynamic ways
to display material to any age group. If you don't find one that pleases
you, any US library can borrow from any other library in the US (if the
books are allowed to circulate-not reference). They can put a search in
for you at no expense to you (other than the tax dollars you already
paid!). They would also put in a search for "Museum Displays."
