The main image is what you would see when you entered Sweet Ups, a Williamsburg bar, in 2004. The painterly treatment was meant to evoke the interior lighting of the bar while the crosshatching was meant to evoke the daylight coming in through the opened door.
The two onion-spheres were drawn for Super Duper Ham: Day One in 2008/2009 and were added to this image in 2011.
