Walt Disney World: The First Decade

This is a souvenir book, not an independent look at the parks.
I got it used from somewhere and as an extra treat, I found a ticket to the Magic Kingdom for a day in 1997 when a child ticket cost $33.00.
It's a nice book as a souvenir, lots of pictures and explanations of the 1.5 parks that were open then.
The parks at the time were The Magic Kingdom and Discovery Island.
EPCOT was still to come.
My favorite part of this was the discussion of the technology involved and the underground facilities.
Look for it on abebooks.com, at this time it can be had for under $10.
