Believe in People has left his mark inside a Yale building.

New Haven’s favorite anonymous graffiti artist went to work this weekend in Room 211 of Linsly-Chittenden Hall. By the morning he had produced an image on the room’s back wall of a young person struggling with his decision to pursue a career in finance. The young man in the image has repeatedly written that he will only work in finance for one year. Seven lines in, the writer changes his tone, and says he will only work finance for two years.

A tipster said a graffiti stencil outline was in place in the room by 3:30 p.m. on Saturday. According to a 3 a.m. tweet from Believe in People himself, several Yale students stumbled across the artist at work this morning — and encouraged him to keep going.

Though Yale administrators have taken a firm stand against BiP’s graffitti in the past, the art had not been removed as of 1:00 p.m. today.
