Ali Graham is the creator of the 99 Problems blog. In July, we flew to London to interview him about his journey creating the work and how it’s been received around the world. Over the past few months, Ali has been illustrating the 99 Problems of Jay Z. The 99th problem is about to be unveiled, bringing the series to an end. On Monday morning, we’ll be posting our interview with Ali, along with a behind-the-scenes look at what goes into creating each illustration. Until then, check out his site to see how many of rap references you pick up on.
