1950's Mucha Mocha Cola cold coffee ice-cream float

I found a 1959 pamphlet recipe book from "Every woman's family circle" magazine at a thrift shop for a dime! There are some strange recipes in there! The Mucha Mocha Cola one caught my eye. Coffee with Cola?! I had to try it.
Dissolve 1/2 packet single serve instant coffee into 1/4 C milk (17gr).
Stir in 2 Tablespoons chocolate syrup
Put this mixture into a glass
Add 2 scoops of Coffee flavored Ice cream
Fill to the top with cold Cola of your choice. (I only needed 6oz)
Top with whipped cream and a bit more of chocolate syrup
