The second image shows Betty Ann Gunther (at least that is what is marked on the back) in front of one of the entrances. It looks like a busy day at the studio with lots of coming and going.
The next image is a group shot of the ladies of Ink and Paint. Identified on the back, they are Ann Esplund, Ivy Carole, Van Horne, Margaret ?, Mille Minnette. They are quite stylish with their bobbed and curled hair and gorgeous outfits. No wonder the animators were always trying to visit the Ink and Paint Department.
The next two are images of the buildings at the studio. The first shows the large windows of the building for the Ink and Paint Department.
The last image appears to be one of the sound stages.
