This was an idea I had in 2017 but didn't expand on it until 2018. I always planned this to be a series but the problem was getting these envelopes. You wouldn't want to get these on purpose (even if it was an idea that you thought was real cool). You would rack up on fines and possibly get your car booted. (Un)fortunately, a few friends were able to donate some of their envelopes and I finally got enough to do a small series.
These things were hard to draw on because it had a coating on them where it made the ink immediately smear as you write on them. Luckily, Sharpie markers and gel pens worked really well.
