I visited the Kyoto Manga Museum recently. There was an activity called Sketchtravel Workshop where participants each drew a picture involving a cat character looking for its sketchbook, and above is what I drew. This may end up in a book collecting the drawings... or something.
The participants at the table. I like their expressions.
