These are straight from my grandmothers button box. I believe most of them are from the 1970's.
2 large mustard colored, 1 large brown marbled, 1 large clear, 7 small brown
The mustard colored ones may be from the 1960's. They are a very unique color. The large brown is marbled on the top with lots of depth. The clear one takes on whatever color it is next to. This one could also be from the 1960's. The seven small ones have lots of depth of color.
