Everyone knows the lovable face of former 2016 presidential candidate Bernie Sanders — white hair, thin-rimmed glasses — but you may be less familiar with the Senator's look as an aspiring politician.

In honor of Sanders' 75th birthday this year, let's look back to when he was just a 23-year-old student pursuing a degree in political science at the University of Chicago, where he had transferred after attending Brooklyn College from 1959 to 1960. Check out this yearbook picture from 1964:

Sanders graduated in 1964 and eventually became the mayor of Burlington, Vermont, from 1981 to 1989. He was then elected to the House of Representatives in 1991 and was elected as a Senator in Vermont in 2007.

On top of his long career in politics, this throwback picture makes it clear that Sanders had some excellent style in the '60s. Happy 75th, Bernie!
