With today's A Genuine Fishing Smack, we're celebrating summer flings for 20x200's Vintage Editions. No, you're not seeing double, collectors. A Genuine Fishing Smack is a stereogram, a turn-of-the-century optical illusion meant to illustrate depth perception. To see this charming edition as intended, look at the image and cross your eyes ever so slightly until a third, 3D image appears in the center. Then you can properly take in this romantic view of a silhouetted couple embracing behind a sail, as the still waters and the sun's beams set the scene.
