This chalk alphabet riddle is puzzling, but we have eyes on the street. Step by step, we’re getting closer to the answer.

One of our regular contributors, Blake, doesn’t think it’s a riddle/code. But he’s been keeping his eyes open for new examples. He found a copycat today, right next to E is for “entropy” on Liverpool Street, Darlinghurst.

And Blake seems to have caught the (original) alphabetic graffitiist in the act:

Lex and I came across this copycat graff this afternoon right next to E is for Entropy and started chatting to another couple who were admiring the work. One of them had seen the culprit in the act! He was described as male, with a beard, carrying a shoulder bag-satchel type thing and an English Staffordshire Terrier by his side.

We’ve had another eyewitness account in the comments, from Nathan:

On Wednesday evening, a surreptitious man was seen on the corner of Hardie and Liverpool Streets, before producing a large piece of chalk from his pocket and wielding it in front of an innocent group of bricks. His accomplice was an unleashed wolf on lookout. The man left the scene and may or may not have a fake beard.

Copycat graffiti! Eyewitness accounts! We’re getting close.
