Vintage Monmouth Maple Leaf Stackable Stoneware Mug Set Butterscotch These mustard yellow / brown stackable mugs are just like grandma had! They were made by the Monmouth/Maple Leaf pottery company from Illinois. They are stoneware and thus, extremely satisfying to hold. These speckled cuties are space savers that will add a quaint touch to your vintage mug collection. These mugs each individually measure at about 3.25” tall and 3.5” wide. When stacked, the set measure at just under 5.5” tall. They are in pristine condition and have been cared for with love. One mug has a slight crack in the glaze in the interior part of the handle (see the last photo). Connect with questions or offers! Peace and love - Jill
