This is an unused image of SDH that I originally drew for the scene on pages 42 through 50 of my 2009 comic Super Duper Ham: Day One. The planet was drawn for panel 3 on page 44. I painted it over for this collage.
The dust in the background was originally drawn for panel 1 on page 35 of my 2010 comic Martian Debut.
The three images were collaged together on another piece of paper with some white paint in 2011.
I added some color and more ink in 2015.
