The first photograph is of Walt Disney holding a model of a Jungle Cruise launch with the concept artwork for the entrance to Adventureland in the background and some African masks anf an elepahnt model sitting on the shelf. I believe this image is from Disneyland: A Progress Report/Natures Half Acre shown on television in 1955.
The second image is of the iconic Disneyland model, Sleeping Beauty Castle. It appears the model was used to promote the Disneyland Television Show in ABC Channel 7 in Los Angeles. I believe this photograph may have been taken at a convention or maybe even the Los Angeles County Fair. The map in the background is a nice touch. This model has appeared in various retrospective museum shows.
