When my coworker saw a drawing I'd done in my apartment, she asked if I could make one for each of our 70 co-workers. Yes, obviously. They were used in a small exhibition about our work.
They were also put all together on a poster in the break room. What I didn't anticipate was that they would be edited. People saw it as an opportunity to add their personal touches to their own drawing. It became a hilarious source of conversation in the break room.
