I put this here because it is local for Southern California and I don't know where else to put it!
Visit this site to get info on "Pencils 2 Pixels - The Art of Animation" exhibit at the L. A. County Fair in Pomona.
This exhibit features animation artifacts from many different studios, but the Walt Disney Family Museum has its own special space. There is an admission price to the fair itself (but there are discounts galore at the fair website), but the animation exhibit has no additional charge. (There is also a Star Trek exhibit that costs five dollars.)
You've got until September 29 to see it. The fair is closed on Mondays and Tuesdays.
