The 1968 version of:  WALT DISNEY'S DISNEYLAND A PICTORIAL SOUVENIR AND GUIDE is often misidentified on eBay as being from 1963. 

The confusion stems from the fact that the cover photograph of Walt Disney signing and autograph is copyright 1963, while the guide itself is copyright MCMLXVIII (1968).

Why it was credited this way, one can only speculate.  It must have made sense to the lawyers.  At any rate, this guide is the first Disneyland guide to be published after the death of Walt Disney in 1966, and as a tribute to the man who built the park, this photo was chosen to adorn the cover.  The photo originally appeared in a 1963 issue of National Geographic magazine, and was taken by Thomas Nebbia.


The actual 1963 guide is titled WALT DISNEY'S GUIDE TO DISNEYLAND and is pictured above.
