Long ago in 1996, when I was 21, I participated with good friend Robert-Jan Langenberg in the Delft Comic Strip Competition. He wrote the scenario, I made the drawings.
Halftone pattern foil
Earlier I participated on my own and already had won prizes. In 1996 my birthplace Delft existed for 750 years. That was also the theme of the comic book drawing competition. And Delft is also the city where comic book shop and co-organizer of the event, Bul Super, was located.
To obtain super sharp drawings, each half of the final A4 page was drawn on an A3 sheet of paper. The 2 x 2 halves were then stuck together and copied to get the maximum number of two A4 pages.
No color was allowed. To get nice grayscale after copying, I used sticky sheets / foil with halftone patterns.
We won the first prize.
