These are made of colorful plastic plastic and the shakers have their original plastic stoppers in the bottom. The salt shaker has three holes at the top, and the pepper shaker has a single hole. The maker of these is unknown but they were created in the 1960s or early 1970s when many Artists like Gig, Keane, Igor, Eden, Lee, Sherle, and many others were creating similar big eyed or sad children, kitten, puppy, and animal art works. To judge the sizes the shakers each measure about 3'' tall. These appear to be in mint unused condition as pictured.
