I did these sektches in the holidays when I was a kid in 1990. I bought several Batman Comic books and started to draw these. Some of them are a part from the Comic Cover where the price is in the left upper corner and most of the comics these days had also a sketch in there. They were very little but this was not an obstacle for me and the poses were great. I chose these and started to draw with a charcoal pencil and after it I also did the Line art.
