This is a French magazine called Ciné Revue from May 25, 1951. It is your basic movie magazine, but large format 11x14. This particular issue has an amazing four page article on the making of Alice in Wonderland.
This mag is chock full of live action reference photos, some of which I've not seen in any other publications, and lots of art taken directly from model sheets too.
If you look closely at some of the photos, especially the large one of Kathryn Beaumont holding the kitten and the one with Walt, you can see some Mary Blair concept art.
The photos of Kathy and Bobby Driscoll in various locations are pretty fun too, since they were probably already recording the voices for Peter Pan at this time. The photo of them outside the Brown Derby is particularly cool.
