I think they had a disagreement...
(my friends and I like to challenge each other to draw random little scenarios like this...try it, it's pretty fun!)
A long time ago In Egypt you would bury the person with some belongings you think they would benefit in their after life. A few interesting objects I chose were from a mobile, baked beans, kitkat, toothpaste, apples, gloves to a paintbrush and more. A fun artwork where egyptian hieroglyphic symbols were used.
I drew this when I was tired of people not doing anything to help the earth even when some people put in so much effort, some people just don't do a thing because it might cause inconvenience.
I wanted it to look like the chalkboard menus in quirky cafes. I drew the image with a Blackwing pencil, scanned it into Photoshop, inverted, then applied the colors.
