An oldie from 1999. Black & white ink on photocopied zip-a-tone, reworked in Photoshop. This was never published, but these were supposed to be the Troglodytes' former masters from my Troglodytes series (1999-2007).
The moire effects are carefully doctored. I used to do that a lot, until all copymachines became digital, which ruined the results. Later, the same thing happened when my books were printed digitally. Thank you, digital revolution.
