Mustache
One of the works you can see during the exhibition 'Pop to Present' in the Cantor Arts Center (Stanford, CA) is a charcoil drawing from a man. It just looks like a black and white photograph!
Cantor Arts Center is open Wednesday - Sunday, 11 am - 5 pm, Thursday until 8 pm. Admission is free. Parking is $0.75 per 30 minutes and free after 4 p.m. (all day on weekends).
