Elon Musk as you've never seen him before in candid pictures taken by his university girlfriend in the 1990s

• Previously unseen pictures of Elon Musk are being auctioned by his college girlfriend.
• He and Jennifer Gwynne dated in 1994 and 1995 when he studied at the University of Pennsylvania.

They might have dated almost three decades ago, but Elon Musk's university girlfriend has decided that now is the right time to sell pictures she took of him back then.

Musk and Jennifer Gwynne began dating in the fall of 1994 when they both lived in a dorm at the University of Pennsylvania, according to Boston-based RR Auction.

Take a look at the collection, which includes a love note from Musk to Gwynne. It has attracted a bid of more than $6,800 - by far the highest so far.

The auction ends on September 15.

The necklace Musk bought as a Christmas gift for Gwynne, but later said it was an early birthday present because she hadn't gotten him anything.

Gwynne once told The Independent that Musk was not "very sentimental and emotional," so when he gave her the necklace "it meant a lot to me because he was opening himself up."
