Disneyland Monday - I Like Disneyland Button

I believe this dates from the 60's and I can't remember from where I picked it up, possibly at a booth at the old Disneyana Convention.  This is a lenticular button displaying two images.  The first is Mickey Mouse and the other is the phrase "I Like Disneyland".  The image below displays a little of both at the same time.

Back of the button telling us that it came from the Art Corner at Disneyland.
