This is from a newspaper clipping found in that old recipe box. Since
Eisenhower (as well as Mamie) left office in 1961 it's a fair shake to say
this newspaper clipping is pretty darned old The recipe was apparently
listed in a number of "ladies" magazines during her husband's tenure at the
White House and probably underwent many changes.

Mamie Eisenhowers Million Dollar Fudge

4-1/2 c. sugar
2 Tbs. butter
1 tall can evaporated milk
Boil 6 minutes

Put in large bowl:
12 ounces German Sweet Chocolate [I'm guessing that's what I know as baking
chocolate for German chocolate cake]
12 ounces semi-sweet chocolate
1 pint marshmallow cream
2 cups nutmeats

Boil boiling syrup over ingredients in bowl. Beat until chocolate is all
melted and pour in pan. Let stand a few hours until cutting. Store in tin
box.
