From 1923, a bunch of looneys posed on top of the Overhanging Rock in Yosemite National Park. It's 3,300 feet straight down off the edge of that rock.
Then there is this photo of the writers Tom Wolfe and Kurt Vonnegut on a lifeguard tower.
And finally a delicious photo of the Mexican artist Frida Kahlo. See if you can pick out her trademark.
O.K. fellows. Be honest now. How many of you noticed Frida's famous unibrow?
Have a fantastic weekend everyone.
