Have you seen J.K. Rowling's 'Harry Potter' sketches?

Obviously J.K. Rowling is an unparalleled writer – but did you know she could draw?
We shouldn't be surprised that her pen-to-paper talents extend beyond crafting words to creating magical sketches. A slew of Harry Potter-inspired illustrations by J.K. Rowling herself are apparently scattered throughout Pottermore.
Without dates, it's difficult to know when they cropped up on the site, but hey, they're new to us.
