The top background image was originally drawn for panel 9 on page 9 of my 2010 comic Martian Debut. The bottom background image was drawn for panel 9 on page 1. The hands putting a condom on a banana was drawn for panel 1 on page 20.
These drawings were collaged together in 2011 on a piece of paper covered in gray paint with some yellow and orange marker. I added the red and blue paint in 2015.
