Although the Walt Disney Company celebrates the anniversary of the release of Alice in Wonderland on July 28th, it in fact had its world premiere on July 26th in London. Here we have a photograph of Walt and Kathy at the world premiere, Kathy in her fanciest Alice costume and Walt looking smashing in his tux.
The premiere was at the Leicester Square Theatre in London, and they went all out for the displays as you can see in this photo. Notice how the accompanying short is Beaver Valley; in the US it would be replaced by Nature's Half Acre. If you look carefully, you'll see that several of the display pieces are enlargements of pages from the Big Golden Book.
Man, what I wouldn't give to have this World Premiere poster, even if the art of the Cheshire Cat is a little scary.
The Leicester Square Theatre is still in use today, although it is now known as the Odeon West End Cinema.
