This is my first submission to the site.
When my family first got a computer (an IBM PCjr back in the 1980's) I used to draw pictures using PC Painbrush. I had no idea it was called pixel art - only that I had a lot of fun drawing it pixel by pixel.
This piece was done in the mid to late 1980's and was actually converted from PCX format. All of the dithering was done by hand, but, using programs like GraphicsGale, could probably be done better today. The picture uses the 16 standard colors available in PC Paintbrush (which, interestingly enough, I think you can still type pbrush.exe to launch Paint today).
Oh, and the subject matter is a giant robot by the name of Dynamo Joe. He had a shortlived comic book back then -- maybe about 5 or 6 issues.
