For anyone who's interested, I've posted a trip report for April 24, 2005 which includes pictures of the new Opera House facade, new Mother's Day 2005 small plush, Disneyland 50th logo on foods paper products, graduation merchandise, new 50th celebration badges and extensive pictures of new "homecoming" 50th celebration merchandise line and another new 50th celebration merchandise line and new castle playset.
Here's the link.
Thanks!
