I'm calling these fish tanks, albeit empty ones. If you don't buy that description, then they are still cool plastic one piece shakers from the 1960s-70s. The top clear lid slides to reveal the "S" shaped or "P" shaped pour holes for the salt and pepper, respectively. The sets are only about 2.75'' in height. These two versions have painted flamingos on the front. I don't know if other examples exist that are painted differently. They have a long marking on the bottom of each that says "Touch Master Styled in California by Norbert Shaeffer MFD. By Albert Rashkow & Associates Los Angeles, Calif. Made in USA".
