The listing, Vintage 1978 Sears Merry Mushroom pieces has ended.
Vintage Merry Mushroom pieces by Sears, Roebuck, and Co. These pieces are all marked from 1978 as you can see in the photos. I believe that they are a napkin holder, a creamer, and a sugar bowl. I have not cleaned these pieces, leaving that to the buyer so that you will know what has been done to them. The creamer has a small chip/nick in it that I tried to photograph. I did not see other problems with the four pieces.
