The Fullerton That Ate Orange County

I saw this promotional map in the background of an otherwise fairly unexciting photo and had to blow it up and check out the details. I've seen some pretty exaggerated maps in my day, but this one takes the cake. Look at the SIZE of Fullerton! It stretches from the desert to the sea (apologies to the late Jerry Dunphy) and from Newport Harbor to Long Beach Harbor! In fact, Fullerton seems to fill the entire county north and west of the Irvine Ranch,... and then some. Does anyone have an actual copy of this map they can scan, so we can see more details?
