Funny Face Fight (Nancy Drew Notebooks)

A FUNNY FACE IS NO JOKE!
The race is on for president of Nancy's class, and three kids are in the running: Vicki Wolf, Jessie Shapiro, and Mike Minelli. But taking sides seems to mean making enemies, and now someone's playing dirty.
Who put the silly mustache on the campaign poster? Nancy has to find out before election day because everybody's getting upset . . . and if everybody's mad, nobody wins!
