Excellent set of 4 vintage Pyrex Cinderella "Amish Butterprint" nesting mixing bowls.  Turquoise and white in color.  This is a very well cared for set, if I do say so myself! It was a wedding gift to my parents in the early 1960s.  One bowl or another was used almost daily, but the good news is...we didn't have a dishwasher, so the print is in excellent condition. There are some light utensil marks inside, and these black scuff marks here and there on the outside of a couple of the bowls. It must have been from storage, I haven't tried to remove them.  The largest one was used most, the white bottom is yellowed a bit, I didn't try to clean that either.  This is really a great set and I'm so excited to pass it on to another family!
