Probably not the correct area to post this and I trust the proper authority will move to the right file. I saw this while conducting (still further) research on the Disneyland Hotel. Thought it was pretty neat and wanted to share with you all. Also wanted to show that I am not so one dimensional (Disneyland Hotel) and am interested in many things Disney. Hope you like this as much as I did when I found it.
This card is actually signed by Roy O. Disney!
Roy O. Disney, Walt's brother actually attended and spoke at this event which took place in 1968.
