I first drew this image of Reptiliman in 2003. I was revisiting the character and his skin-tight costume while studying human anatomy. In 2014, I incorporated the image into a new cover for Momentos. I drew the background in 2009 for panel 3 on page 40 of Super Duper Ham: Day One.
The two images were collaged together in 2011 with white paint and some additional ink. Color was added in 2015.
