How to Make the 5th Amendment Cocktail (Common Man Cocktails)

This is certainly a bit unique but has a classic feel. I don't know how to describe it. I definitely have to taste it one day due to the bitters, branca, and falernum.

Recipe
1 3/4 oz. Bourbon whiskey
1/4 oz. Yellow Chartreuse
1/4 oz. Fernet-Branca
1/2 oz. Velvet Falernum
2 dashes Passion Fruit Bitters
Garnish: Lemon peel
