Whoever put this video together deserves a medal.
These are images from '70s love manuals paired to the Magnetic Fields song "The Book of Love," not to be confused with the "Oh I wonder wonder who-o-o-o who (bum)" song. The song comes from the 69 Love Songs album, three CDs of music from every possible genre that fit at least two definitions of the word "genius." And Peter Gabriel's cover version has the distinction of singlehandedly making the Richard Gere / Jennifer Lopez film Shall We Dance worth your while.
As to the images... well, they don't make 'em like they used to, do they?
