If you have been bitten by the True-Life Adventures history bug like I have, you will be glad to know that this book exists since John Ott worked on The Secrets Of Life and Nature's Half Acre and since My Ivory Cellar seems to contain a few pages about those two projects.

This just in from Steve Maslowski, son of one of Disney True-Life Adventures cinematographers, Karl Maslowski:

[Attached are three photos - one which shows my father with Walt; another shows my father with a woman in a boat taken during the filming of an old show called "Secrets of Earthquake Lake" at Reelfoot Lake in Tennessee. The woman apparently was one of the stars. A third photo shows my father a few years earlier in the same area on his way to build a tower to photograph nesting egrets. If I remember right, some of the film Dad shot then was subsequently used in Secrets of Earthquake Lake.]
