Studio art pottery penguin bird salt and pepper shakers

Studio art pottery penguin bird salt and pepper shakers. Some of my photos did not appear so they were accidentally deleted but the top of the Shakers have holes in them and the salt there are holes in the shape of the letter S and then the pepper there are holes in the shape of the letter P and the holes are in excellent condition. These are wonderfully handmade but they have no stoppers currently ... I did not get them with stoppers in the bottom so if you want to use them you're going to have to put something in the bottom yourself but there are no cracks chips or repairs now it looks like there were some cloth or some kind of bow ties glued under the chins because the remnants of the glue is there and the potter made a little indentation for the glue so I think they look fine just the way they are ! I never saw what was under their chin but it was probably a.bowtie? They are vintage but I don't know how old they are.
